AIX 3.2.5: DCE threads get internal deadlock error with shared memory
Question:
System Configuration:
AIX 3.2.5
AIX DCE 1.2
dcepthreads 1.1
The customer is just using DCE for thread support for an application that
uses shared memory and semaphores. The application is single threaded.
They receive the following error:
internal dce threads problem, terminating execution.
reason: enter_kernel: deadlock
see ma_dump.log for state information.
Response:
Eventhough the application is single threaded, the AIX 3.2 DCE threads
package will use several threads itself. AIX 3.2 shared memory and
semaphores are not thread safe.
