How did you configure force_send_sock? it should be something like this: modparam("siptrace", "force_send_sock", "sip:192.168.1.210:5066 <http://192.168.1.210:5066>") I'm guessing instead of sip, you are putting udp...

I have a siptrace module configured like modparam("siptrace", "duplicate_uri", "sip:<MY_HOMER_SERVER>:9060") modparam("siptrace", "hep_mode_on", 1) modparam("siptrace", "trace_to_database", 0) modparam("siptrace", "trace_on", 1) modparam("siptrace", "hep_version", 3) modparam("siptrace", "trace_mode", 1) When Kamailio is under stress test (sipflood via OPTIONS/TLS), with this settings it transfers all flood to HOMER server. At some point Kamailio just stops accepting any new TLS connections. Turning off siptrace solves this issue. As I got, siptrace module is not changing protocol of the message (means not converting TCP/UDP) or so. Could it be possible, that at some point siptrace "eats" all TCP connections (especially if remote HOMER is down or not answering) which leads Kamailio to stop processing any new connections? And is it possible to send HEP traffic only via UDP to prevent this? Yes, sure other option is to trace only "legal" traffic -- Best regards, Ihor (Igor) __________________________________________________________ Kamailio - Users Mailing List - Non Commercial Discussions sr-users(a)lists.kamailio.org Important: keep the mailing list in the recipients, do not reply only to the sender!
