            <title>[CDRIVER-1439] Deal with spurious wakeups from pthread_cond_wait</title>
                <link>https://jira.mongodb.org/browse/CDRIVER-1439</link>
                <project id="10030" key="CDRIVER">C Driver</project>
                    <description>&lt;p&gt;From the manpage of &lt;tt&gt;pthread_cond_wait()&lt;/tt&gt;:&lt;/p&gt;

{block}&lt;br/&gt;
When using condition variables there is always a Boolean predicate involving shared variables associated with each condition wait that is true if the thread should proceed. Spurious wakeups from the pthread_cond_timedwait() or pthread_cond_wait() functions may occur. Since the return from pthread_cond_timedwait() or pthread_cond_wait() does not imply anything about the value of this predicate, the predicate should be re-evaluated upon such return.{block}

&lt;p&gt;Basically, &lt;tt&gt;pthread_cond_wait&lt;/tt&gt; can return whenever it feels like! Our code in the mock server (and maybe elsewhere) doesn&apos;t deal with this case, and it should.&lt;/p&gt;</description>

&lt;p&gt;Message: &lt;a href=&quot;https://jira.mongodb.org/browse/CDRIVER-1439&quot; title=&quot;Deal with spurious wakeups from pthread_cond_wait&quot; class=&quot;issue-link&quot; data-issue-key=&quot;CDRIVER-1439&quot;&gt;&lt;del&gt;CDRIVER-1439&lt;/del&gt;&lt;/a&gt; handle spurious wakeup in mock server&lt;/p&gt;

&lt;p&gt;Not a verified bug, but for correctness, re-check the condition after&lt;br/&gt;
cond_wait when starting a mock server&apos;s background thread.&lt;br/&gt;
