<tt>Hi Jonathan,<br>
<br>
It looks like you have kind on task inside OpenSIPS that is using
a lot of time/process resources - shortly, this translate into
"there are no available worker processes to handle new jobs".<br>
<br>
* do you have any threshold set to catch any DB/DNS delays ?<br>
* have you checked the CPU usage ?<br>
* have you monitor the "load:" statistics group ?<br>
<br>
Regards,<br>

</div>
<div><br>
</div>
<div>Has anyone had the following behaviour with this release of
opensips?</div>
<div><br>
</div>
<div>It has been running fine for a number of months, and then
suddenly today the server which was running as the primary
suddenly stopped responding to SIP requests, or stopped
processing them, or there was a long pause in a sequence
completing.</div>
<div><br>
</div>
<div>So in some cases, INVITES or REGISTER messages were ignored
and the initial requests werent always logged in the opensips
log file (even though we do this for all messages), however
the SIP requests were hitting the server as I was tracing
them.</div>
<div><br>
</div>
<div>In the logs I can see the following warnings we havent seen
before;</div>
<div><br>
</div>
<div>Oct 30 13:31:25 sgw6 VU-SIP-Proxy[11159]:

<div>Oct 30 13:52:48 sgw6 VU-SIP-Proxy[11159]:
WARNING:core:timer_ticker: timer task <ul-timer> already
scheduled for 9640980270 ms (now 9641175280 ms), it may
overlap..</div>
<div><br>
</div>
<div>A restart of the opensips application didnt help, and
service was only restored fully when I failed over to the
secondary server.</div>
<div><br>
</div>
<div>Has anyone had these issues before? There are no obvious
server level issues, and as I mentioned the logs dont contain
anything too unusual.</div>
<div><br>
</div>
<div>Any help appreciated.</div>
<div><br>
</div>
<div>Many thanks</div>
