<tt>Hello,<br>
<br>
The tm-utimer is the timer job performing the SIP retransmissions.
And OpenSIPS reports an overload of this timer - basically 100ms
were not enough for OpenSIPS to finish doing all the needed
retransmissions. This is not an error, but an warning telling you
that there are too many retransmissions to be performed, eating a
lot processing cycles. <br>
<br>
I guess that the retransmissions are due some issues with the SIP
traffic ?<br>
<br>
Best regards,<br>

<div>Hello all,<br>

I have a Pentium 3 Proxy server, configured with the
opensips, any time I want to send more than 500 message
per second via the proxy I get this warning and a lot of
retransmissions occur. Here is a part of the log file: <br>

BTW, I have searched through the Internet, I have increased
the children to 12, but the problem still exist. I also
don't have a radius server which was another solution given.<br>
</div>
I really need help.<br>
</div>
Thank you<br>
