[OpenSIPS-Devel] [opensips] error in infinite loop "io_watch_del: BUG - trying to del fd 34 with flags 2 1" (#591)

[rgupta0110]

I have captured logs for the scenario and uploaded to zippyshare . Please let me know if you want me to upload to anyother location 

http://www76.zippyshare.com/v/njlgk4lW/file.html

1) netstat_debug.log --- netstat info for the particular endpoint (10.205.203.130 in this case)
2) opensipsctl_debug.log --- list_tcp_conns  from opensips for the particular end point (10.205.203.130)
3) opensips.log --- opensips logs with debug level 6


Call flow and timestamps :
1) 15:45:02 --- created a TCP connection to send out SIP NOTIFY to 10.205.203.130
2) 15:46:30 --- unplugged the network cable from the endpoint 10.205.203.130
3) 15:47:11 --- tcp connection timed out (FYI tcp_connection_lifetime=120 in opensips.cfg)
4) 15:49:30 --- Tried another call to the same end point while the network cable was unplugged. opensips created another TCP connection to send another SIP NOTIFY, netstat showed this connection in SYN_SENT state
5) 15:50:31 --- the above connection went away from net stat and opensips started printing  "BUG - trying to del fd 34 with flags 2 1" in infinite loop


FYI, I changed the debug level of this message from ERR to DBG in source code and recompiled so that it doesnt fill my hard drive while running in debug=2 mode

Let me know if you need more clarification or any other details regarding this issue

Thanks
Rahul Gupta
