Saving core dump to non-volatile directory

[munduk75]

Hi,

One of my customers had a very bad LS crash today (v4.0.11) and received 75 warnings by email :

At [11/Jan/2010:15:10:01 +0000], web server with pid=34503 received unexpected 
signal=11, a core file is created. 
A new instance of web server will be started automatically!
....
If the call stack information does not show up here, 
please compress 
and forward the core file located in /tmp/lshttpd/.

However, by the time I was informed and could connect to their server, they rebooted it !! So, no more core files, they are all gone

All I have left is a single line in error.log :

2010-01-11 15:16:33.101 [WARN] [AutoRestarter] forking too frequently, suspend for a while!

Wouldn't it be a good idea to save those files to a non-volatile dir instead of /tmp ?

You can configure the core file location with
/proc/sys/kernel/core_pattern

or corresponding sysctl directive.
