Are 1800 volumes too many? We have been experiencing TCP connection

Andy - You obviously need to look for ANR messages in the TSM server
Activity Log for cause.
Keep in mind that the parallelism gained through an increasing number of
storage pool volumes exacts some overhead: for every such volume
there is
a server thread (DiskServerThread, as seen via SHow THReads). A high
number, on top of TSM's threads complement for its other activities, may
be pushing the per-process threads limit defined in your operating
system.
