Re: [asterisk-users] kore dump
For anyone interested on the crashes I was experiencing when using ChanSpy from SIP extension to SIP extensions with the group option. For the last couple of days, Ive been monitoring from Zap extensions to SIP extensions, and the system has not crashed once. The problem only happens when I spy from SIP.

Re: [asterisk-users] kore dump
What is a god Windows application to read core dump files? Microsoft jokes aside, I would seriously doubt there could be a good Windows application for analyzing core dumps. Due to the OS specific nature of core dumps, the need to have the source files, debugger and more, would make it difficult. I'm not saying there isn't one, I've just never heard of one. When developing software modules, I've had some success using crash on Fedora systems. Though as a whole system, a review of the logs to see what was changed just prior to getting the core dumps has been more effective at isolating the problem than the analysis of the core dump.

Check the directory in which you're starting Asterisk. It doesn't sound like you're using the Red Hat initscript to start Asterisk, so you're probably starting it manually. I'd check there first. I would also like to know if Asterisk can be setup to automatically re start if there is a core dump. I was thinking of setting up a cron job to launch Asterisk every minute. If it's running, no harm done, and if it crashes, the cron job will make sure that it's started every 60 seconds. Check out the safe_asterisk script that's installed with Asterisk. Again, I recommend you check out the initscript, which calls safe_asterisk and restarts Asterisk if it crashes. It also ensures that your core dumps end up in /tmp where you can find them more easily. On Red Hat and CentOS, you can install the initscript by typing make config in the Asterisk source directory. -Jared ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] kore dump
Ed, I am having a problem with Asterisk frequently crashing on me as well. I just run it under supervise: http://cr.yp.to/daemontools/supervise.html This way it will be restarted if svc determines it isn't running.

Re: [asterisk-users] kore dump
I am having a problem with Asterisk frequently crashing on me as well. I just run it under supervise: But that's just a band-aid. If it crashes, it takes all calls with it. Hardly a good thing, unless you only have 1 call at a time -- then it's probably no the end of the world. I still don't know what's up with the crashes but here are two observations I made: 1) I moved the same installation from one hardware to another. On the former hardware it would crash every 2 weeks, on average. On the new hardware, it has not yet crashed and it has 9 weeks of uptime. Same call volume, same devices, same network. I'm running asterisk chroot'ed so all libraries, binaries, config files, etc. are identical. Only the hardware and kernel are different. 2) The same old hardware has been in service for 3 years and no other programs crash on it. Ever. It's no unusual seeing uptime for say qmail, samba or bind of 200+ days. I have therefore reasons to believe that the hardware is OK. So go figure. And BTW, the crashes (based on the core dumps) are always at a different place. There is no consistency. Right now I'm just glad it no longer core dump on me :). --Luki ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [asterisk-users] kore dump
just an idea, but maybe qmail, samba, and bind have a smaller memory footprint than an in-use asterisk? can you take the hardware offline long enough for a memtest?

Re: [asterisk-users] kore dump

Asterisk's is about 20-40 MB depending on the number of extensions, etc. Smbd's is similar, bind's is actually 90 MB (with about 600 zones). can you take the hardware offline long enough for a memtest? The machine has been retired (routine upgrade cycle). But I hardly doubt that was the problem. My guess is it was somehow related to limited CPU power (thread switching, interrupts, or whatnot). The old hardware was single CPU and a lot slower. --Luki ___ --Bandwidth and Colocation Provided by http://www.api-digital.com-- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
