<tt>Hi Rodrigo,<br>
<br>
The issue you are reporting it is not the real problem, but a side
effect of it. As you noticed, when opensips is under heavy load
(CPU?), the internal timer system starts to generate warnings you
see.<br>
<br>
Now, the questions is: why is your opensips using 100% or why is
it blocked (no processes available). Do you have any input on this
?<br>
<br>
Regards,<br>

<p>Hi.</p>
<p><br>
</p>
<p>I have seen again that behavior from OpenSIPS that generates
lots of warnings, like below:<br>

When it happens, I can see that OpenSIPS is using the CPU
almost 100% of the time. And such behavior prevents others
softwares in my system to work without problems. I see 6
process with 'OpenSIPS name and each one using 11% of CPU, for
example. Now, the unique solution is to reboot the system.
Otherwise, the system remains instable and OpenSIPS continues
using the CPU much more than usual.<br>
<br>
Is there some new information about such issue that I should
to know nowadays?<br>
Is my hardware under minimals requirements to run OpenSIPS?<br>
Is my script opensips.cfg wrong?<br>
<br>
My system has the following characteristics:<br>
<br>
CPU clock = <span>996000<br>
<span> CPU <span>model name = ARMv7 Processor rev 10
(v7l)</span></span><br>
