<div>In your case were the error messages immediately preceeded by "error: could not event_del on close"?</div>

<pre>After downgrade to 1.8.1 with an unchanged configuration file the </pre>

<pre>I replaced 1.8.1 (known to work) with 1.9.2~rc3 on one server that </pre>
<pre>"run crazy" with 1.9.1,</pre>
<pre>At least over 3 days I did not noticed the log message mentioned in </pre>
<pre>$subject - fine.</pre>
<pre><br></pre>
<pre>There are numerous changes between 1.8.1/utils/netevent.c, </pre>
<pre>1.9.1/utils/netevent.c</pre>
<pre>(that may introduce the failure I saw) and 1.9.2/utils/netevent.c</pre>
<pre>(that may solve the issue again)</pre>
<pre>Does this sound reasonable?</pre>
