&lt;p&gt;&lt;b&gt;ISSUE SUMMARY&lt;/b&gt;&lt;br/&gt;
MMAPv1 on Windows has a known race condition during flushing that is reported to the log file as:&lt;/p&gt;
&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;

					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;[durability] MapViewOfFileEx for ... failed with error errno:487 Attempt to access invalid address. (file size is ...) in MemoryMappedFile::remapPrivateView&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;[durability] Fatal Assertion 16148&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;&lt;b&gt;USER IMPACT&lt;/b&gt;&lt;br/&gt;
This race condition exists in Windows version of MongoDB&apos;s MMap storage engine, and prevents MongoDB from properly managing memory mapped files. MongoDB will shutdown automatically if it detects this result.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;WORKAROUNDS&lt;/b&gt;&lt;br/&gt;
This race condition does not affect storage engines other than MMAPv1. Therefore, to resolve this issue, we recommend transitioning to WiredTiger. Alternatively, since this issue only affects Windows machines, using another operating system would resolve the issue.&lt;/p&gt;

&lt;p&gt;&lt;b&gt;TECHNICAL DETAILS&lt;/b&gt;&lt;br/&gt;
The MMAPv1 (Memory Mapped) Storage Engine relies on the operating system&apos;s memory management system to manage the caching of the database file in 4kb chunks (i.e. pages) in MongoDB&apos;s memory. On Linux, this is implemented with the &lt;tt&gt;mmap&lt;/tt&gt; system call. The operating system automatically reads in pages into memory when accessed, and evicts pages from memory when the system runs low on physical memory.&lt;/p&gt;

&lt;p&gt;One of the features of the MMAPv1 storage engine is the journal. The journal is a sequentially written file used to provide write-ahead-logging (WAL). The journal is used to support recovery of commits in the case of crash in an efficient way.&lt;/p&gt;

&lt;p&gt;In order to support recovery, for each commit made to the database, a description of the change is written to the journal first, next the journal is written to disk, then the database pages are written in memory, and finally the user receives a notification their change is complete. Please note the exact point at which the notification is received depends on write concern.&lt;/p&gt;

&lt;p&gt;In order to ensure the journal is written to disk before the database pages are written to disk, a private copy of each database file is made using the Copy-On-Write (COW) feature of the operating system&apos;s memory manager. Modifications are written to this private copy (which is never written to disk). This is necessary since the memory mapped file can be written by the OS at any time due to page eviction. Later, after changes have been written to the journal, the changes to private copy are copied to the file-backed copy. &lt;/p&gt;

&lt;p&gt;Now, after the pages are copied, the private copy, and the file-backed copy will have the same contents. At this point, MongoDB needs to instruct OS that these two copies are the same, and it can safely discard the copies of the file-backed pages it made.&lt;/p&gt;

&lt;p&gt;To tell the OS these pages are the same, the storage engine calls &lt;tt&gt;x&apos; = mmap&amp;#40;x)&lt;/tt&gt; on the private copy, and requires that the &lt;tt&gt;mmap&lt;/tt&gt; function call return the same address back for the private copy (i.e. &lt;tt&gt;&quot;x` == x&lt;/tt&gt;). On Linux, the &lt;tt&gt;mmap&lt;/tt&gt; function has this behavior.&lt;/p&gt;

&lt;p&gt;On Windows, there is no direct equivalent of the &lt;tt&gt;mmap&lt;/tt&gt; function with the required behavior. The solution is a two step operation on Windows via &lt;tt&gt;UnmapViewOfFile&lt;/tt&gt;, and &lt;tt&gt;MapViewOfFileEx&lt;/tt&gt;. Because it is a two step process, there is a window for other components in the MongoD process to make calls into the Windows memory management system, and prevent &lt;tt&gt;MapViewOfFileEx&lt;/tt&gt; from being able to use the same address again. Examples of this are new thread creation, Windows Heap allocation, TCMalloc allocation, and Mozilla Javascript memory allocation. If &lt;tt&gt;MapViewOfFileEx&lt;/tt&gt; fails to map the private copy at the requested address, MongoDB terminates with the following fassert:&lt;/p&gt;

&lt;p/&gt;
&lt;div id=&quot;syntaxplugin&quot; class=&quot;syntaxplugin&quot; style=&quot;border: 1px dashed #bbb; border-radius: 5px !important; overflow: auto; max-height: 30em;&quot;&gt;
&lt;table cellspacing=&quot;0&quot; cellpadding=&quot;0&quot; border=&quot;0&quot; width=&quot;100%&quot; style=&quot;font-size: 1em; line-height: 1.4em !important; font-weight: normal; font-style: normal; color: black;&quot;&gt;
		&lt;tbody &gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;  margin-top: 10px;   width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;[durability] MapViewOfFileEx for ... failed with error errno:487 Attempt to access invalid address. (file size is ...) in MemoryMappedFile::remapPrivateView&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
				&lt;tr id=&quot;syntaxplugin_code_and_gutter&quot;&gt;
						&lt;td  style=&quot; line-height: 1.4em !important; padding: 0em; vertical-align: top;&quot;&gt;
					&lt;pre style=&quot;font-size: 1em; margin: 0 10px;   margin-bottom: 10px;  width: auto; padding: 0;&quot;&gt;&lt;span style=&quot;color: black; font-family: &apos;Consolas&apos;, &apos;Bitstream Vera Sans Mono&apos;, &apos;Courier New&apos;, Courier, monospace !important;&quot;&gt;[durability] Fatal Assertion 16148&lt;/span&gt;&lt;/pre&gt;
			&lt;/td&gt;
		&lt;/tr&gt;
			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;

&lt;p&gt;Unfortunately, there is no known solution to this issue other than workarounds described above.&lt;/p&gt;
&lt;/div&gt;&lt;/div&gt;

&lt;h6&gt;&lt;a name=&quot;Originaldescription&quot;&gt;&lt;/a&gt;Original description&lt;/h6&gt;

&lt;p&gt;On Windows, in MemoryMappedFile::remapPrivateView, if the virtual address occupied by the private view is claimed by another thread between the time the private view is unmapped and the time that it is mapped again, the MapViewOfFileEx call will fail with an &quot;invalid address&quot; error, and mongod will terminate. Following messages are diagnostic of this problem:&lt;/p&gt;

A primary already implicitly steps down if it shuts down due to this problem.  Leaving the process up but not responding to read or write requests would not be an improvement over simply shutting the process down.&lt;/p&gt;</comment>

Could it not just clean up memory and recover itself. At the very least, could it not stepdown ( if primary ) and allow replicasets to continue nicely ?&lt;/p&gt;</comment>

&lt;p&gt;Same here, and it seems the frequency of the issue is increasing.&lt;br/&gt;
Any plan for a hotfix ? or at least a fix in a new Mongo release ?&lt;/p&gt;</comment>

Since it is a crash issue, what are the chances of getting a hotfix rather than having to wait/upgrade to a new version altogether?  &lt;/p&gt;</comment>

&lt;p&gt;Any news on a fix for this ? Can get dumpfiles any time you like.&lt;/p&gt;</comment>

Copying files around will not have any effect, as the root cause is connected to details of the memory management subsystem on Windows. If it is possible for you to do so, migrating to the WiredTiger storage engine would be a permanent solution, as that storage engine is not affected by this issue.&lt;/p&gt;</comment>

Say like copying the database into a new file structure - removing the old, and renaming the new db back to the old name.&lt;/p&gt;

&lt;p&gt;Would love a quick win here if possible.&lt;/p&gt;</comment>
