Description:
When a 32-bit distribution of TIBCO ActiveMatrix Adapter for SAP running on a Linux/Unix box may crash when interacting with SAP.
Symptoms:
The size of the core if is about 4GB and the backtrace of the core file provides the following stack trace upon crashing.

Cause:
The stack size from the operating system level is too large (typically is set to unlimited) which will cause the virtual memory size of the 32-bit adapter to increase over 4GB when processing messages.
