            <title>[SERVER-47918] Improve &quot;replSet too much data to roll back&quot; to include reason for &quot;too much data&quot; limit </title>
                <link>https://jira.mongodb.org/browse/SERVER-47918</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;There are two methods used for rollback:&lt;br/&gt;
1. &quot;Rollback to Timestamp&quot; (default)&lt;br/&gt;
2. &quot;Rollback-via-Refetch&quot; - used when &quot;enableMajorityReadConcern=false&quot;&lt;/p&gt;

&lt;p&gt;Under condition #1 the 300MB rollback limit is no longer enforced post-4.0. But under condition #2, the limit is still enforced, and users can still get the following assertions:&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;2020-05-03T00:11:01.079Z F -        [rsBackgroundSync] Fatal Assertion 40507 at src/mongo/db/repl/rs_rollback.cpp 1515&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;2020-05-03T00:11:01.079Z F ROLLBACK [rsBackgroundSync] Unable to complete rollback. A full resync may be needed: UnrecoverableRollbackError: replSet too much data to roll back.&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;It would be helpful to include the information that the rollback limit was enforced because &quot;enableMajorityReadConcern=false&quot;.&lt;/p&gt;</description>
