*
* USAGE: crash.d
*
* FIELDS:
* Type Signal type
* Program Execname of process
* Agrs Argument listing of process
* PID Process ID
* TID Thread ID
* LWPs Number of Light Weight Processes
* PPID Parent Process ID
* UID User ID
* GID Group ID
* TaskID Task ID
* ProjID Project ID
* PoolID Pool ID
* ZoneID Zone ID
* zone Zone name
* CWD Current working directory
* errno Error number of last syscall
