Re: [SR-Users] Segmentation Fault encountered in pv.so

Hi, Since I am getting errors in from the usrloc module, I am trying another way to parse out the information I need using pv.so. I'm encountering similar segfaults issues. Here are snippets of my configs: modparam("sipcapture", "db_url", "mysql://xxx:xxx@localhost/test_db") modparam("sipcapture", "capture_on", 1) modparam("sipcapture", "table_name", "sip_capture") modparam("sipcapture", "raw_socket_listen", "127.0.0.1:5060-9000") modparam("sipcapture", "raw_interface", "eth2") modparam("sipcapture", "raw_sock_children", 4) modparam("sipcapture", "raw_moni_capture_on", 1) modparam("sipcapture", "promiscious_on", 1) route { if (method == "REGISTER") { if (avp_check("$si","eq/10.xxx.xxx.xxx")) { #save("location", "0x04"); # This currently results in segfault and is being addressed by Alexandr sip_capture(); xlog("The received IP is $Ri\n"); # Just to test if I am able to parse the received IP from the Via headers correctly drop; } drop; } } Feb 17 13:41:02 ubuntu kernel: [251382.760104] kamailio[9414]: segfault at 31 ip 00007fb4ef077611 sp 00007fff0c8a6468 error 4 in pv.so[7fb4ef06a000+39000] Core was generated by `kamailio -w /home/core'.
