Using all of the options in the previous message I got the following results when I dropped to the kernel debugger on the hung system: Bunch of stuff I'm assuming isn't important... Xresume1() --- interrupt vop_sharedlock() vn_lock() vrele() nfs_nget() mountnfs() nfs_mount() mount() syscall() Xint0x80_syscall() Now obviously the functions above were actually lines like, vop_sharedlock(bunchofstuffI'massumingarememoryaddresses) at vop_sharedlock(morestuff,etc.) I just ran the test without the "vers=2" option and it's locked up the system again, so I am going to go look at ddb and report back. The machine room is on the other side of the building so I'm shuttling back and forth. I'm also going to try the test with the vers=2 option and without the proto=udp option and see what kind of results I get.
