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;
}
}

Hello,

right, very dummy paste position for resetting the redis context, use
the attached patch or exchange lines 228 and 229. in redis_client.c

Thanks,
Daniel
