Hello,
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.
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.
Also, depending of the config various tunings may be required for
increasing the perormances, such as value of children parameter.
Cheers,
Daniel
