Hello
Are you sure that the SAP system is running ?
This is what I see from the trace files:
M ***LOG Q02=> wp_halt, WPStop (Workproc 0 7030) [dpuxtool.c 269]
M Good Bye (-1).....
SemKeyPermission
More likely an issue with the shared memory.
Check in dpmon the status of the WP's.
Stop SAP and database.
Clean up the shared memory segments using cleanipc.
What Linux distribution are you using ?
Also check the swap space configuration.
Good Luck
