Hi Jayesh, The trace shows your opensips is blocked in doing a DNS query.
I guess you have some domain name which get a very long timeout in query - this long timeout keeps an opensips processes blocked until timeout fires or gets an answer I suggest to set up a local DNS server (as proxy) to force a very low timeout on queries (to avoid blocking all opensips processes in DNS). This majoe problem is to be fixed in new opensips 2.0 version.
