I ran the 'echo t' command recommended below once afs hung again. It definitely put some output in dmesg. The only D states that were listed were bash sessions (I think). It looks like they were sessions that I opened after the user told me that afs was hung again. I tried to attach the dmesg output and cmdebug output but the email was rejected because the log files were way too big. Any ideas of what to try next? Or is there anything in particular that I should look at in the cmdebug or dmesg output. Thanks,

Call traces for all processes can then be found in dmesg. The broken processes are probably in a D state. This will probably not identify the root cause, but may give a clue about what's going on.
