I started to get this and a few more Dr. Watson errors after I upgraded from ADSM 3.1 (NT) to TSM 4.1 For some reason there was a SCSI error with the library. I have since tried to upgrade to 4.1.3 with no luck. I again uninstalled everything involving TSM and reinstalled including importing my data base, a long dragged out process. So far so good. FYI... I also had (for some unknown reason) my drives (3575 - IBM) replaced due to them going offline and marking most of the tapes read-only. Their firmware was upgraded on them, but I still believe there were communication errors being reported back to TSM Server. Ever since this was done I have had very few problems (on the server side). I was then experiencing problems with a few clients that are having problems communicating with TSM Server 4.1.3, their sessions just keep timing out (currently set to 300 seconds). New client installs have not solved this problem, however I have installed the old ADSM 3.1 on my test server and tried to backup, and of course the problem does not exist.
