No quotas, low usage. Nightly dumps hung last weekend, and any new dumps (till I rebooted) hung. Other process' access to the drives seemed ok, but hung dump processes were unkillable. Sorry, didn't have any debug stuff turned on, so I realize this info is of limited or maybe even no use. Hadn't seen this before. If it crops up again, I'll build a new kernel for debugging and try and get more data. thanks jim
