We've had lots of problems with Netware TSM clients in general at all different sorts of levels for both TSM and Netware.
But I just wanted to suggest that one possible solution, which has solved a lot of our problems with TSM clients abending and hanging (and otherwise acting crappy) has been this one: http://www-1.ibm.com/support/docview.wss?uid=swg1IC45554 Basically, it says the actual syntax is: NWUSER <server>\<username>:<pass> and not this: NWUSER <server>:<username>:<pass> (note the '\'). Where pass is optional if you have nwpwfile specified. The APAR says that 5.3.0 clients are affected, but I know that 5.2.x clients are affected as well, on both Netware 5 and 6.
