[sr-dev] PCSCF does not send SIP 200 OK

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 ?
