received tcp message. I would try to run ser in debugging with remote logging. If the problem still occurs (with the extra debugging overhead), you might have a chance to see what ser sees and break the problems.

is ser able to log 3000 requests/second or logs it only the failed message?

WL.

I feel this is more appropriate for serdev.

Hi!

Scenario: sipp sends INVITE to ser, ser replies with 404. sipp sends
3000 INVITEs per second with TCP. sipp + ser on the same machine,
packets will be snet over loopback device.

Suddenly ser reports a bad message:

Jul 26 16:39:31 t4000 ser[14152]: ERROR:parse_first_line: method not
followed by SP

Jul 26 16:39:31 t4000 ser[14152]: ERROR:parse_first_line: bad message
  > rtpmap:0 PCMU/8000 087637 IN IP4 83.136.32.91sg:

Jul 26 16:39:31 t4000 ser[14152]: ERROR: receive_msg: parse_msg failed


Although the message captured looks fine:

Any hints for the problem debugging?
