Error description
The system will hang when it tries to acquire a lock which is held by a process that no longer exists. The stack can look many different ways. Below is one example: pvthread+000200 STACK: [0021A38C]krlock+000264 (000000000101B128, F10001002CCD71A8 [??]) [003021A4]slock_krlock_acquire+0001E8 (??, ??, ??) [0030297C]slock+0004E0 (??, ??)
