<p>Hi Bogdan.</p>
<p><br>
</p>
<p>Thank you for answering the questions.</p>
<p><br>
</p>
<p>In fact, today I moved my project to another hardware (2 CPUs and 516 MByte of RAM) and then I was able to see that OpenSIPS is working very well spending almost 0% of the CPUs. So there is no problem with the script opensips.cfg.</p>
<p><br>
</p>
<p>On the other hand, we have a sip client (softphone implemented by us) that even on this new environment it spends almost 100% of CPUs during calls. So, this softphone has a problem that was preventing the OpenSIPS to use the CPU in a normal way, as I suppose.
In this case, I will focus my attention in such softphone for a while. Hopefully, by solving such issue, the entire system will run well even with 1 CPU and 256 MByte of RAM.</p>
<p><br>
</p>
<p>Best regards.</p>

<div><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>

<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>
