You can try sending the stalled process a signal to force it to dump core.
You need to be root to do this if your account is not running the process.
where xyz == pid of process
If you have seen other core dumps by the account the process runs under then you are good to go. Otherwise check back here and a red hat person can step you through setting up core dumps.

We have an application that terminates with segmentation violation errors in the logs. No source code is available since this is a third party software that is way past its maintenance life cycle. Under these circumstances is there a way to force a core dump of the process for further analysis??

I know I've installed Nagios open source before, I though it's only for that kind of thing. I never though that Red hat ent 4 would be like client/server on the crash dump.

CORE(5) BSD File Formats Manual CORE(5)NAME
core -- memory image file format
SYNOPSIS
#include <sys/param.h>
DESCRIPTION
A small number of signals which cause abnormal termination of a process also cause a record of the process's in-core state to be written to
disk for later examination by one of the available debuggers. (See sigaction(2).) This memory image is written to a file named by default
core.pid, where pid is the process ID of the process, in the /cores directory, provided the terminated process had write permission in the
directory, and the directory existed.
The maximum size of a core file is limited by setrlimit(2). Files which would be larger than the limit are not created.
The core file consists of the Mach-O(5) header as described in the <mach-o/loader.h> file. The remainder of the core file consists of vari-
ous sections described in the Mach-O(5) header.
NOTE
Core dumps are disabled by default under Darwin/Mac OS X. To re-enable core dumps, a privileged user must do one of the following
* Edit /etc/launchd.conf or $HOME/.launchd.conf and add a line specifying the limit limit core unlimited
* A privileged user can also enable cores with launchctl limit core unlimited
* A privileged user can also enable core files by using ulimit(1) or limit(1) depending upon the shell.

A core file format appeared in Version 6 AT&T UNIX.
