[users@httpd] apache2 stack trace
Hi all, some help on the following stack trace would
be appreciated.
Relevant info:
Red Hat Enterprise 4
Apache 2:
httpd-2.0.46-57.ent
------------------------------------------
Httpd is crashing quite frequently on a server.
The stack trace is always:
(gdb) bt
#0 0x00442067 in ___newselect_nocancel () from
/lib/tls/libc.so.6
#1 0x010056d9 in cm_sleep () from
/usr/local/netegrity/webagent/bin/libmod_sm20.so
#2 0x01006b8e in ConnectionService () from
/usr/local/netegrity/webagent/bin/libmod_sm20.so
#3 0x00360dd8 in start_thread () from
/lib/tls/libpthread.so.0
#4 0x00448d1a in clone () from /lib/tls/libc.so.6
------------------------
To my untrained eyes this appears to be related to
spawning a new thread.
If correct, could increasing Max Threads help or just
make the situation worse?
Thanks,
Frank

The crashing module is CA SiteMinder (it was called "Netegrity SiteMinder" before CA acquired
Netegrity) - so it is apparently a SiteMinder problem, not an Apache problem.
You are more likely to get useful help from CA than from Apache folks for your libmod_sm20 module.
