We use OpenNMS to monitor, but Nagios looks like an interesting product. The restart is a bit more complex as the process has to be killed with a "-9" as it does not die easy... R.

BTW: You can use Nagios or a similar tool to collect various data from the system and find a coincidence between events. You can even monitor status port responsiveness and restart the gatekeeper if necessary. I am working on a better resource control, but this will definitelly take some time, as the task is complex. ----- Original Message ----- From: "R. Todd Wallace" <rwallace@xxxxxxxxxxxxx> Sent: Wednesday, February 09, 2005 6:39 PM We have done some more research and it seems that Radius is idle when the GNU becomes non-responsive. We can issue requests to radius and it responds which seems to take Radius out of the picture. What might be a problem is that the GNU cannot free up a socket for a radius request. I can't tell if we are running out of Processor Cycles, Memory or sockets. We have ULIMIT's set, FD's set and everything looks typical of systems mentioned. We have a ton of traffic on these and do hit low asr periods on particular routes. When it becomes non-responsive, I can hit the status port, but it just gives a blank screen like it is waiting on response. I enter commands and they just echo on the screen. I am not sure if the GNU is aware of its resources, but it sure would be nice if it would just reject requests until that resource is freed up. A patch as you suggested would be great! R.

Maybe the number of sockets is the problem as Michal stated, but I think that if it is then Gnugk should be patched so that it can recover from the lack of socket resources instead of the entire process just becoming non-responsive.

It hasn't happen to me yet on 2.2.2. When this happens nothing is responsive. When you check the cpu usage for the Gnugk process it stays at zero, and the calls begin to drop while all incoming calls never get connected. Also this has happen to me with about 500 calls in h225 routed mode (with tunneling) only. I usually run 3 to 4 times more calls on Gnugk per server. So I don't think it's a socket issue or a cpu issue since cpu usage in routed mode its relatively low when I'm running 1500 to 2000 calls on my servers I'm at about 24 percent. I believe I posted this same problem a few months back. This issue doesn't happen very often. I once noticed that it did happen to me when I issued a debug trace on the status port, the system became non-responsive like the symptoms just described.

Check port ranges and current socket usage and per process socket limits (netstat, ulimit). If you're using acct/auth, make sure your backend is not a bottleneck. ----- Original Message ----- From: "R.
