Error description

  • The WebSphere Application Server for z/OS server instance
    appears to run out of storage when using the OTMA support of
    the Optimized Local Adapters (OLA) in an environment where
    Java threads are created and destroyed frequently.  A
    CORBA::NO_MEMORY exception is seen in the servant region
    output.  The servant region may terminate and a new servant
    region may replace it.

    *                      region may run out of storage and       *

    * RECOMMENDATION:                                              *
    ****************************************************************
    The Optimized Local Adapters (OLA) component caches a work
    area for each servant region task which uses OTMA.  This work
    area is not cleaned up when the task terminates.  If tasks are
    created and terminated frequently, this can lead to an out of
    memory condition, causing the servant region to stop taking
    new work, or causing the servant region to terminate.  The out
    of memory condition is reported by a CORBA::NO_MEMORY
    exception, which can be seen in the servant region output
    (SYSPRINT).
