When the machine locked it was running a background fsck. I saw "Giant" > a lot in the status of the nfsd. 'k, you are going through something similar to me, it seems ... have you implemented the stuff on: http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug-deadlocks.html and: enabled DDB within your kernel? (man ddb) ... DDB is required for the deadlocks debugging ... also, is this a machine you have 'easy hands on' for? (ie. in my case, I'm dealing with remote servers, which is *really* fun) ... Actually, what you will want to do is setup a serial console if you can, so that you can 'trap the output' of the commands that stuff like ps and all that will throw out from DDB, unless you *really* like to write? I can help you get this all setup offlist if you wish, just email me and we'll work through the steps required ... once you have a debug environment in place, then generating a good/complete/in depth problem report is easier ... ---- Marc G.
