Hi all,

I am trying some Kamailio IMS load tests.

I have an issue with SIP.REGISTER when 10-11K registrations are done.

PCSCF start slowing down responses. I increased my test tool (sipp) timeouts, but still there are some missing SIP.OK from P-CSCF to SIPp. S-CSCF and I-CSCF SIP.OK are present, only some P-CSCF SIP.OK are missing and SIPp closes the dialog(2-3 sec timeout)

I have compared a successful and unsuccessful registration and for now it seems like t_on_reply is not executed the right way.

Did anybody meet such a problem ?
