smbmount shares not lasting

[Gregory Leblanc]

I've got a machine running RedHat Linux 6.2 on a P-II400 with 256MB of ram.
I'm mounting shares in the manner 'mount -t smbfs -o uid=user,gid=group
//server/share /mount/point'.  The server is a genuine NT 4 server, with SP5
and a couple of hotfixes.  I mounted a couple of shares yesterday, and
overnight the stopped working.  When accessing the share, I get an error
message that says "ls: /mnt/gleblanc: Input/output error".  I don't see
anything in the logs as to why this is happening.  Got any ideas?  Thanks,
	Greg
