Error description

• A STORAGE RELEASE in CSQ3SSI1 abends S378-0000000C when trying
  to release key 7 storage due to incorrectly specifying the
  storage key.
  
  After an instance of this problem, S378-0000000C abends may
  reoccur during EOT for tasks which are allocated the same ASID
  as the HOME ASID of the originally abending task. This
  recurrence of the problem may affect tasks which never connected
  to an MQ QMGR.
  
  S073-0000000C, S073-00000010 and SB78-00000018 abends may also
  be seen in CSQSINTM after an initial instance of this problem.

  ****************************************************************
  The code that requests this storage release does not specify
  which key the storage is in. As a result, the code attempts to
  release storage in the wrong key, causing an abend.
  

Problem conclusion

  it is attempting to free. As a result, the abend will no longer
  occur.
