Solaris 2.5 core dumps on boot

I have a sparc 20 running solaris 2.5; it seems to have
memory leakage, but I don't know from where. This forces me
to reboot the system on a weekly basis- but on reboot,
I get a core dump right after fsck, (mount related?) and some file partitions specified in /etc/vfstab are not mounted. I run many applications off this machine (it's a server) including SunNet Manager, Remedy  ARS Client,  Optivity Fault correlator, and Netscape. Can anyone help me?

Determining the cause of the core file is relatively easy with the "file" command:

file core

Will tell you the program that produced the core file, and the signal that caused it to core. Check the man pages for the program, to see if it handles that signal. If it's something unexpected, like a SIGSEGV, then you should seriously consider opening a call with Sun.

However, it sounds like it is probably fsck, so I would suggest booting into single user mode, then doing a full fsck on each of the file systems (individually), and determine where it is falling apart. (Shut the machine down to the boot prompt, and boot -sm). fsck errors would explain why the file systems are not being mounted, but you should be forced into a root shell to check the file systems.

Hope that's enough to get you going.
