smbmount intermittent problems

[Hieb, Michael]

I use smbmount to mount a number of NT shares from around a global network
in order to sync from a master distribution which resides in linux.
Specifically...

uklnxsrv$ smbmount //NTSRV/share -c 'mount /tmp/temporary_mount -u 502 -g
510' -U guest%guest_passwd

Frequently it works well, but from time to time the mounted NT share, for
lack of a better word gets corrupted. Here are the symptons

1.	trying to access the directory gives the following error.

		uklnxsrv$ ls -la /tmp/temporary_mount
		ls: /tmp/temporary_mount: lstat failed: Input/output error

2.	If you try to access /tmp you do not see the mount, but get the same
error...

		uklnxsrv$ ls -la /tmp
		ls: /tmp/temporary_mount: Input/output error
		total 2
		drwxr-xr-x   3 aigfpdev aigfpdev     1024 Jul 14 08:00 .
		drwxrwxrwx   3 aigfpdev aigfpdev     1024 Jul 14 07:57 ..

3.	Syslog reports the following errors

	Jul 14 05:23:51 uklnxsrv kernel: smb_retry: signal failed, error=-3 
	Jul 14 05:23:51 uklnxsrv kernel: smb_lookup: find //Risk failed,
error=-5

	Jul 14 05:23:51 uklnxsrv rdist[27307]: uklnxsrv: REMOTE ERROR:
/tmp/temporary_mount/document.doc: lstat failed: Input/output error


The network is fairly slow <250 Kbs/sec, the problem is intermittent and not
always between London and Tokyo, sometimes to New York, sometimes to Paris,
etc...

I am using RH6.0 and Samba 2.0.3-8.

Please help, what is wrong, how can I deal with it?
