Thread unsafe code in Socket adapter on Unix 64 bit platforms could cause the Launcher or Command Server to core dump

Technote (troubleshooting)


Using the IBM WebSphere® Transformation Extender Socket adapter in any multi-threaded maps under the control of the Launcher or the Command Server could cause a core dump.

Resolving the problem

The core dump files indicate that the function that crashes is strncat.strncat() at 0x100045698. Partial stack trace listing:
