  * PROBLEM DESCRIPTION:                                         *
  * Abends may occur in an application address space when the    *
  * queue manager is configured with a non-zero ACELIM setting   *
  * and the ACELIM limit is reached. The queue manger            *
  * subsequently terminates with an S6C6-00F3040C abend.         *

  ****************************************************************
  An S0C1, S0C4, or S0C6 abend may occur in the application
  address space or Channel Initiator address space after exceeding
  any configured ACELIM limit for the queue manager when
  attempting to issue the CSQY228I console messages. The invalid
  PSW address when cross referenced to the queue manager address
  space will be at entry to the CSQFGENM module. This problem is
  caused by a failure to perform a space-switch before attempting
  to issue the console message.
  

Problem conclusion

• Processing has been amended to ensure that a space-switch to the
  queue manager address space is performed when necessary, prior
  to issuing the console message.
