****************************************************************
The ABEND378 occurs in module BBOSSEXT while attempting to free
a Native Security Context that was freed. This double free
occurs because of a race condition between 2 threads while
processing multiple identities for the WepSphere for z/OS
plug-in.
Problem conclusion
The processing of multiple identities via a local session was
modified to be thread safe. Multiple identities are now saved
safely, instead of being deleted when identities do not match.

APAR PQ57800 is associated with SERVICE LEVEL W401035 of
WebSphere Application Server V4.0.1 for z/OS and OS/390.
