I am continuously receiving following error in the logs instead of disabling the sip trace module

captagent: [ERR] protocol_sip.c:132 Couldnot find this call

and when I restart the service there is a warning in the logs 

Nov 18 20:33:47 kamailiostandby SIPSer[5495]: WARNING: tls [tls_init.c:781]: init_tls_h(): openssl bug #1491 (crash/mem leaks on low memory) workaround enabled (on low memory tls operations will fail preemptively) with free memory thresholds 17301504 and 8650752 bytes
