Yes, I have one customer using the TSM 3.7 (ADSM in the past) on NT 4.0 SP5 with the same problem on QualStar TLS 4440 library(40 cartridges + 2 drives). The resolve was to fix TSM 3.7.0.0 to 3.7.3.0. In 3.7.3.0 configuration the server work fine without freezing and offline tapes. _______________________________ Boris Feldman - Product Manager IBM Storage & TSM UDI Millenium Ltd. 1G Yoni Netanyahu Str.

We have the same problem! If the library does something stupid and stops responding, eventually, ADSM server hangs....then all the ADSM clients hang. It's a !@#$% nuisance. Hopefully someone has resolved such a problem. Alan Cheski Gulf Canada Resources
