Hi Rick, From my experience, I had problem with an Expire inventory process (was hanging on a very large node in term of items > 13 millions ) that froze TSM but it was on 6.1 version. Also, REORG can use a lot of resources an impact TSM.

Envoyé : 16 juillet 2014 11:08 À : ADSM-L@VM.MARIST.EDU Objet : [ADSM-L] TSM server appears to hang Hi Everyone, The past couple of days we're had a strange problem with one of our TSM instances (v6.2.5). At times it appears to hang. Last night (and the previous night) it had many servers that got a dozen or more sessions. This is really strange! This morning as I was looking at this, cmds like "q vol" and "q stgpool" hang - no response! Commands like "q node" and "q proc" work. The server was doing very little I/O. All of a sudden the hung cmds all ran through and the server I/O jumped to 200-400MB/s. Something was locking I/O. I think the many sessions are clients that retry because the server is not responding. In the TSM actlog there are no unusual messages about the time it un-stuck. The only strange entry in the actlog is a ANR9999D with lockwait error early the previous evening. There are no AIX errors. Any thought?
