There was a lot there; what should I be looking for?Hard to tell ... one starting point could be looking at a process which you known is hung with ps/a. This will give you its proc structure address. Then you can get a stack trace with tr/a Another way, if you see lots of processes waiting on tstile, would be to start with show all tstiles. Once you found the lwp which holds the lock causing the hang, get a stack trace of it.
Alright, that sounds like just the thing. Thank you so much, Staffan
