[users@httpd] segfault with no dump
Hi,
I am stack with trying to debug segfaults happening almost every
seconds.
The problem is that the child process always dies without creating a
dump file.
Of course, I did configure this directive in httpd.conf (note that I am
running Debian 6.0):
CoreDumpDirectory /tmp/apache-dumps
I ended up setting the following rights :
$ ls -la /tmp/apache-dumps
total 8,0K
drwxrwxrwx 2 www-data www-data 4,0K 25 mars 01:27 ./
drwxrwxrwt 9 root root 4,0K 29 mars 14:26 ../
Unfortunately the server is mutualized between several sites and each
has a bunch of pages, so it is not possible to manually find the
culprit.
I am aware of modules like mod_backtrace and mod_whatkilledus, but this
is a production server where I can't afford to compile and run these.
At least not before having tried all other possibilities...
So my questions are :
- how is this possible that no dump is created? I am pretty sure
something is wrong in my settings, but I am definitely missing it...
- if ever it is not possible to get a dump, would you have any other
suggestions on how to debug this ?
Thanks in advance,
Best regards,
