            <title>[SERVER-80716] Problem with growing WiredTigerHS.wt file</title>
                <link>https://jira.mongodb.org/browse/SERVER-80716</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;Good morning. In the past week, we experienced an issue with MongoDB 6.0.5 - it&apos;s a replica set consisting of 4 data nodes, each two in different data centers and an arbiter in the cloud. Due to an application error, the WiredTigerHS.wt file grew significantly within a few minutes, filling up the filesystem on 3 of the data nodes, which resulted in a database outage. Since we are currently in the process of migrating a large number of databases from MongoDB 3.6 to MongoDB 6, we would like to find a way to prevent such a situation from happening again. Is there a possibility to move this file to a different filesystem or any other option to prevent a similar situation in the future?&lt;/p&gt;</description>

                            <comment id="5681186" author="JIRAUSER1257066" created="Tue, 5 Sep 2023 20:38:50 +0000"  >&lt;p&gt;Hi &lt;a href=&quot;https://jira.mongodb.org/secure/ViewProfile.jspa?name=rund3ck%40gmail.com&quot; class=&quot;user-hover&quot; rel=&quot;rund3ck@gmail.com&quot;&gt;rund3ck@gmail.com&lt;/a&gt;,&lt;/p&gt;

&lt;p&gt;The history store was introduced in 4.4 and the default parameter &quot;minSnapshotHistoryWindowInSeconds&quot; was increased by &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-47855&quot; title=&quot;Change default value for minSnapshotHistoryWindowInSeconds to 5 minutes&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-47855&quot;&gt;&lt;del&gt;SERVER-47855&lt;/del&gt;&lt;/a&gt; in 5.0. This may explain why WiredTigerHS.wt may have increased across versions.&lt;/p&gt;

&lt;p&gt;To further investigate this issue, we&apos;d like to encourage you to start by asking our community for help by posting on the &lt;a href=&quot;https://www.mongodb.com/community/forums&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;MongoDB Developer Community Forums&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;If the discussion there leads you to suspect a bug in the MongoDB server, then we&apos;d want to investigate it as a possible bug here in the SERVER project. Since this behavior appears to be working as designed, I will now close this ticket.&lt;/p&gt;

&lt;p&gt;Kind regards,&lt;br/&gt;
Edwin&lt;/p&gt;</comment>

This Jira project is for standalone WiredTiger users - I&apos;m moving the ticket to a more appropriate Jira project for triage.&lt;/p&gt;</comment>
