Obtain the fix for this APAR.

APAR status

Error description

• A SLIP trap set for ABEND378 captured a dump for an ABEND
  378-00000018 for a RELEASE from CSQ3RSRB to free the module's
  dynamic storage. The problem is that the storage is being
  released with CALLRKY=YES while running in the wrong PSW key.
  The problem happens every time the module is called, but the
  abend does not dump or write to LOGREC without the SLIP.
  
  The problem was introduced at IBM MQ for z/OS V9.2.4 (a
  Continuous Delivery or CD version) and is included in the
  V9.3.0 base code level.
