Hello,<br>
<br>
I expect that the log message from sip trace means that a
retransmission was detected and it is not going to be sent to
sipcature server.<br>
<br>
Printing the log messages for memory operations (malloc/free) is
going to be very costly in terms of performaces, be sure that
parameters memlog/memdbg are lower than debug.<br>
<br>
Also, depending of the config various tunings may be required for
increasing the perormances, such as value of children parameter.<br>
<br>
Cheers,<br>
Daniel<br>
