| Summary | 0002618: Random Crash | ||||
| Description | We got an awful crash today on one of our server, apparently linked to some kind of DNS stuff. core file was generated (still available) & useful backtrace is in "Additional Information" section ;) Somebody told me to say "Looks like unitialized memory" to look smart ;p using gcc 3.3.6 and glibc 2.3.5 | ||||
| Steps To Reproduce | Impossible - random crash - not even precise context/reasons | ||||

could you paste the contents of /etc/resolv.conf? (you can xx out the last 2 parts of the ips...) |
|
|
yep, here it is.. $ cat /etc/resolv.conf search xxx.net nameserver 127.0.0.1 nameserver 213.246.33.xxx nameserver 213.246.34.xxx nameserver 213.246.33.xxx really not exceptionnal, uh ;) |
|
|
heh, just had nobody crashing with 127.0.0.1 as dns yet.. but that could be "coincidence" :P. -- Could you send me the core file + src/ircd binary + commands.so? [email protected] Thanks. |
|
|
You got mail ;) |
|
|
Hi, we got another crash during the night, on another server. (physically different machine, same unreal version) I can provide the ircd file, the core file and the backtrace if needed, but it'll be almost the same ;) |
|
|
Thanks. I'm still interested in that, so if you could send those files (or the url) to me, that would be great :). I'm trying to find a pattern in the crashes. |
|
|
I'll mark this one as a dup... So please use bug 0002499 for further correspondence (or email). -- Still interrested in the new cores though :). |
