I've been running into similar sorts of deadlocks on my diskless crash boxes, and have dropped some information to Don on them. Try the following also from ddb: print numvnodes print desiredvnodes print vnlruproc_sig print vnlru_nowhere This will print some information on the number of active vnodes; one of the characteristics of my nfs client/server box in its deadlocked state is that it has exceeded the maximum number of vnodes, presumably by necessity.
