You could change your asterisk command to asterisk -vvg, but this will eat your disk space if you have a large number of faults since each core.* file produced takes up 1-13 Mb. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Steve Edwards Sent: Monday, March 02, 2009 9:08 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [asterisk-users] How to generate core dump?

Hi Ken, If you run ulimit -c on the command line and get a 0 output, then you need to run ulimit -c unlimited on the command line. -Steve Ken D'Ambrosio wrote: Asterisk segfaulted on me the other day; how do I tell it to generate a core file so -- if it happens again -- I can attempt to debug?

Re: [asterisk-users] How to generate core dump?
You would think this, but I've seen asterisk create 100 or more dumps in an hour of 10+Mb. Depending on Inode size, etc., this situation could push a system into a hurting capacity rather quickly. Also, many shops use older technology and compound this by RAID striping, which can reduce your effective capacity by up to 70%.

I looked in the obvious places in make menuconfig and didn't see anything appropriate. There should be a file called something like backtrace.txt that gives you instructions on how to compile with debugging options, generate a coredump when Asteriss crashes, as well as information on how to generate a backtrace to determine where the problem is located. This file would be in the doc/ directory in your Asterisk source. -- Eric Wieling * Asteria Solutions Group * Huntsville, AL Call centers * IVRs * Enterprise PBXs * Conferencing applications 256-705-0277 * http://www.asteriasgi.com/ * sa...@asteriasgi.com ___ -- 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

Just an observation. 100 crashes an hour is one thing, that will fill up somewhat quicker, but still, it's only slightly less than a gig per hour, it'd be days before most modern system started to run out of space if they have the entire drive formatted under / I have a e-mail system on 100GB RAID 5 system (4 36GB drives) that has never run out of inodes and it's receiving a few hundred files per minute, heck, looking at it it's only using 5% of inodes for 50GB of small e-mail files. You'd have to be running some old Red Hat (pre 8) to have a standard ext3 format not have enough inodes (for a mail server). I really don't see any reason to run RAID 5 on an Asterisk server when mirroring might be a better option and it'd give you faster overall file IO. I'd hate to see a four or five drive RAID 5 system rebuild if it had 100GB drives, a coat of paint probably dries faster. -Ron ___ -- 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
