Any errors in syslog ? At my company we run automunter as well
mostly on CentOS 4.x, and RHEL 4.x, though some newer systems are
on 5.x. The only time I get that kind of error is if a firewall
is blocking the connections, and there is always an error in syslog
saying that it couldn't connect to the NAS.

e.g.

Jan 22 02:52:24 pd1-cas01 automount[32591]: >> mount: mount to NFS server
'exnas' failed: timed out (giving up).
Jan 22 02:58:42 pd1-cas01 automount[23530]: >> mount: backgrounding
"exnas:/exavol/system_logs/syslogs"

How many systems do you have mounting the NetApp? Here we are migrating
from a BlueArc based system to an Exanet based system, NetApp's
architecture limits it's performance too much for our needs(and price
point). Maybe with OnTap 8.0 with the integration of GX stuff it
will be better.
