First you need to enable cores so that you can see what causes the crash (and be sure of the process that is crashing), as root
Code:
mkdir /cores
echo "/tmp/cores/core.%e.%p.%h.%t" > /proc/sys/kernel/core_pattern

This will give you core file names that "just make sense(TM)"


Unfortunately the next step is a little complex, you need to run
Code:
gdb -c $core_file_name -e $path_to_named_executable_in_core

This will at least give you the reason for the crash
next run
Code:
gdb> bt -all

this will let you know what was happening at the time of the crash, however gdb is a bit arcane for someone whose knowledge of Linux is limited

NAME
gzexe - compress executable files in place SYNOPSIS
gzexe name ... DESCRIPTION
The gzexe utility allows you to compress executables in place and have them automatically uncompress and execute when you run them (at a penalty in performance). For example if you execute ``gzexe /usr/bin/gdb'' it will create the following two files: -rwxr-xr-x 1 root root 1026675 Jun 7 13:53 /usr/bin/gdb -rwxr-xr-x 1 root root 2304524 May 30 13:02 /usr/bin/gdb~ /usr/bin/gdb~ is the original file and /usr/bin/gdb is the self-uncompressing executable file. You can remove /usr/bin/gdb~ once you are sure that /usr/bin/gdb works properly. This utility is most useful on systems with very small disks. OPTIONS
-d Decompress the given executables instead of compressing them. SEE ALSO
gzip(1), znew(1), zmore(1), zcmp(1), zforce(1) CAVEATS
The compressed executable is a shell script. This may create some security holes. In particular, the compressed executable relies on the PATH environment variable to find gzip and some standard utilities (basename, chmod, ln, mkdir, mktemp, rm, sleep, and tail). BUGS
gzexe attempts to retain the original file attributes on the compressed executable, but you may have to fix them manually in some cases, using chmod or chown. GZEXE(1)
