System Panic Message VFS_REMOVE

[News Administrator]

I am using a rm command to empty a file system through a crontab entry, which
causes the system (sparcstation running SUNOS Rel. 4.0.3c) to panic 
and reboot !!

The Panic message written in the /usr/adm/messages file looks 
like this : vmunix: panic: vfs_remove: vfs not found

The shell script which does that looks like :

	.........
	mount /dev/.... /mnt
	cd /mnt
	for i in * ; do rm -rf $i ; done
	.....
	.....

The script bombs and leaves a core file behind which  says that the 
rm command bombed.

Any ideas, views , suggestions are welcome .

Thanks in advance.
