Any executing image can core dump. It may be one of the ulimit settings for the iplanet webserver user(s). -- I do not know iplanet.
logon or su to the user.
if coredump is set to 0 no core will be produced, for example. If disk quotas are enabled and the quota in question is nearly used up, core may not get created as well. core has to do with user and system-wide settings.

Hi guys,
just want to know which core file pattern is best to set for core dumps:

kgdb
KGDB(1) BSD General Commands Manual KGDB(1)NAME
kgdb -- kernel debugger
SYNOPSIS
kgdb [-a | -f | -fullname] [-b rate] [-q | -quiet] [-v] [-w] [-d crashdir] [-c core | -n dumpnr | -r device] [kernel [core]]
DESCRIPTION
The kgdb utility is a debugger based on gdb(1) that allows debugging of kernel core files.
The options are as follows:
-a Increase the annotation level. An annotation level of 1 features the historical -fullname option of gdb(1). This is useful
when running kgdb in Emacs. The -f or -fullname options are supported for backward compatibility as well.
-b rate Set the baudrate to rate.
-q Suppress printing of the banner when the debugger starts. The -quiet form is supported for compatibility as well.
-v Increase verbosity.
-w Opens kmem-based targets in read-write mode. (This is identical to what --wcore used to do in previous gdb versions for
FreeBSD.)
-d crashdir Use crashdir instead of the default, /var/crash to locate kernel core dump files in. The name vmcore. plus the dump number will
be appended to determine the actual dump file name.
-c core Explicitly use core as the core dump file.
-n dumpnr Use the kernel core dump file numbered dumpnr for debugging.
-r device Use device to connect kgdb to for a remote debugging session.
The -c, -n, and -r options are mutually exclusive.
Optionally, the name of the kernel symbol file and the name of the core dump file can be supplied on the command-line as positional argu-
ments. If no kernel symbol file name has been given, the symbol file of the currently running kernel will be used. If no core dump file has
been specified through either of the options or the last command-line argument, /dev/mem will be opened to allow debugging the currently run-
ning kernel.
FILES
/dev/mem Default memory image to open if no core dump file has been specified.
/var/crash Default directory to locate kernel core dump files.

The kgdb utility first appeared in its current form in FreeBSD 5.3.
