Greetings all,
I have a problem with my Samba server seeming to hang for 10
seconds every 5 minutes or so. Client machines also become
sluggish across the entire network during this period. It
does not seem to affect file transfers that are in progress.
Any ideas would be greatly appreciated.

Greetings all,
I have a problem with my Samba server seeming to hang every 5 minutes or so.
Client machines also become sluggish across
the entire network during this period. File transfers that are in progress do
also hang, but do not seem to drop.
Any ideas would be greatly appreciated.
