            <title>[SERVER-59219] Investigate whether the RecordStore oplogDiskLocRegister() and waitForAllEarlierOplogWritesToBeVisible() functions can deadlock due to ticket exhaustion</title>
                <link>https://jira.mongodb.org/browse/SERVER-59219</link>
                <project id="10000" key="SERVER">Core Server</project>
                    <description>&lt;p&gt;This is follow-up work from &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-59074&quot; title=&quot;Do not acquire storage tickets just to set/wait on oplog visibility&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-59074&quot;&gt;&lt;del&gt;SERVER-59074&lt;/del&gt;&lt;/a&gt;, where we skip ticket acquisition for &lt;tt&gt;StorageInterfaceImpl::waitForAllEarlierOplogWritesToBeVisible()&lt;/tt&gt; and &lt;tt&gt;StorageInterfaceImpl::oplogDiskLocRegister()&lt;/tt&gt; due to a deadlock from ticket exhaustion while updating oplog visibility.&lt;/p&gt;

&lt;p&gt;There are still other callers that call these functions directly from the &lt;tt&gt;RecordStore&lt;/tt&gt;, circumventing the work in &lt;a href=&quot;https://jira.mongodb.org/browse/SERVER-59074&quot; title=&quot;Do not acquire storage tickets just to set/wait on oplog visibility&quot; class=&quot;issue-link&quot; data-issue-key=&quot;SERVER-59074&quot;&gt;&lt;del&gt;SERVER-59074&lt;/del&gt;&lt;/a&gt;. We should investigate whether it&apos;s feasible to add an assertion in these RecordStore functions that we are not holding a ticket.&lt;/p&gt;</description>
