While I am new to managing TSM, I have tried to research this and have not
found much other than "upgrade to 5.5.2" (we are on 5.5.1). Has anyone else
seen this on you HSM clients?

Client is failing. Event viewer on the client machine is full of

"Journal for fs 'H:' reset:"

and

"Notification buffer overrun monitoring fs 'H:\', journal will be reset."

3.37 GB RAM, 60 GB free on C: anmd at least 200 gb free on each drive.

It was a problem on just one drive (others where apparently working fine),
but just last night it started on another.

It sounds like to me that the server itself is having a problem completing
the clients request.

Any ideas?

Thanks in advance.
