Enable console logging and set the log level to debug (console loglevel debug) iirc, Next, see if you are able to type 'status' into the CLI after it has stopped responding, and make sure it outputs something. Perform a test to see how long it takes for the freeswitch instance to stop responding. Copy all the log entries from the point where it started, to the point where it stopped responding, then attach and send the file to this list. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Once the fs instance has stopped responding, can you please try and construct a SIP packet and send it manually to the server from the local host of the server. You can use sendip to do this, by following the instructions at [1]. Once you send the packet, check to see if it is received by fs. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><p class=MsoNormal>If no packet is being received even when sending from localhost, run "netstat -inp | grep LISTEN | SIPPORTHERE", replacing SIPPORTHERE with the port you are running sip on fs. Ensure that the only entry for udp is th fs instance, and nothing else. For a slightly more deeper approach, attach an strafe to the fs instance, you can do this by looking in the process list for the fs instance, then typing "strafe -ifq -p PIDHERE" replacing PIDHERE with the pid of your fs instance. Attempt to send a call to fs, ensure the packet arrives through wireshark, and see if the packet appears in the strace (this is a really brutal way of debugging sometimes, it doesn't offer all the answers but can give you a bit of an X-ray as to what is going on).<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>Also ensure you eliminate any possible outside interference, such as switch gear or routing equipment.. If possible, connect the windows server and the fs instance directly together, bypassing anything in between.
