how to find reasons for a segfault
Hy all,
I realize that one of the Servers we run writes lots of messages about
segfaults in the logs, like
[Mon Jan 28 20:57:05 2002] [notice] child pid 15373 exit signal
Segmentation fault (11)
Now trying to find out more about this i looked in the faq and searched
the web, but did not find anything that got me further.
My main problem is I do not know where to start looking - how can i find
out if it is one of the loaded modules that causes the Segfaults and if
which one of these?
When i can find out that i can look if somebody else has the same
problem and solved it.
TIA,
henning

Henning,
Not that this works all the time, there are probably othermethods
but what you can do is:
pstree -pa | grep httpd
grab the parent pid # and run
strace -p $pid
then connect. The strace may show you.
or if you are getting a core dump:
file core ( just to make sure its the httpd core dump)
and I believe you can ue gdb on the core file. do a man on it to see
what options.
