Not quite a complete death, but it seems to loose any ability to communicate with the rest of the world. In /var/log/messages I just see endless entries like this: Nov 21 02:00:13 WARNING[18841] chan_sip.c: No such host: voipfone.co.uk Nov 21 02:00:13 WARNING[18841] chan_sip.c: Probably a DNS error for registration to [EMAIL PROTECTED], trying REGISTER again (after 20 seconds) An attempt to connect to the console leaves asterisk eating up CPU cycles and this in /var/log/messages Nov 20 11:51:25 WARNING[94218] asterisk.c: Accept returned -1: Too many open files A message which reoccurs several hundred times a second. Can anyone either solve this problem for me completely, or at least give me a hint as to the significance of 02:00? Is this an Asterisk thing (most of my configurations are as per install samples), or an underlying OS thing? Firstly, look and see what the too many open files are: # lsof -p94218 (or whatever the complaining PID is). I'm assuming FreeBSD has lsof. I don't know, as I use Linux. Next, examine the cron jobs that happen at 2am, to see if any of them could explain anything. Failing that, it could be that something ishappening at your provider everyday at 2am and Asterisk is not coping with it gracefully. You could also try specifying 212.187.162.178 temporarily instead of voipfone.co.uk - that would tell you whether the problem is DNS related.

I'll give this ago tomorrow morning Next, examine the cron jobs that happen at 2am, to see if any of them could explain anything. I did look at that. Nothing seems to run at 2am that doesn't run on every other hour. My first inclination was that maybe newsyslog was trying to rotate Asterisk's logs at 2am, but that doesn't look to be the case. I take it that Asterisk (with mostly the standard sample config files) doesn't try to do anything at 02:00 then? Failing that, it could be that something ishappening at your provider everyday at 2am and Asterisk is not coping with it gracefully. I hadn't considered that. Connectivity provider, or VOIP provider (of the latter I have more than one)? I'll experiment with some debug output overnight tonight to see if it gives me any more clues. You could also try specifying 212.187.162.178 temporarily instead of voipfone.co.uk - that would tell you whether the problem is DNS related. I'm pretty sure it is not DNS related. Asterisk seems to loose the ability to connect to anything, irrespective of the direction of the connection. Phones can not connect to Asterisk either. I think the inability of Asterisk to connect to a DNS server is merely one of the symptons of a total inability to talk to anything else at all. -- Chris Hastie ___ --Bandwidth and Colocation sponsored by Easynews.com -- Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

I take it that Asterisk (with mostly the standard sample config files) doesn't try to do anything at 02:00 then? I don't believe it does anything according to a fixed schedule like that. Failing that, it could be that something ishappening at your provider everyday at 2am and Asterisk is not coping with it gracefully. I hadn't considered that. Connectivity provider, or VOIP provider (of the latter I have more than one)? Could be either. My theory is that something your Asterisk tries to do regularly is failing for some reason at that time, due to something either internal or external, and that the error handling is not closing one or more file descriptors that it had opened. As the failed operation gets retried (possibly quickly and often), these leaked fd's accumulate and eventually reach the process limit. You could also add or uncomment the following line in /etc/asterisk/logger.conf: full = notice,warning,error,debug,verbose (you may have to restart asterisk or do a logger reload) Then you can see what is in /var/log/asterisk/full after the problem has occurred.
