APAR status

• Closed as program error.

Error description

• You are running with z/OS Connect and Liberty.  While the
  environment is mostly idle, after several days CICS reports
  messages DFHSM0133 and DFHSM0142, indicating that CICS is
  short on storage (SOS).  ESDSA was using more than 50MB out
  of EDSALIM 100MB, and the storage is filled with the
  eyecatcher for the SJLRB control block, ">DFHSJLRBBLK".

Problem summary

• ****************************************************************
  * USERS AFFECTED: All CICS users.                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: With idle Liberty JVM server, SJLRB     *
  *                      control blocks get orphaned and are     *
  *                      not freed.                              *
  ****************************************************************
  When the Liberty JVM server starts up, it will allocate a
  number of threads in the thread pool. CICS will create a
  new SJLRB (listener request block) for each thread. In an
  idle Liberty JVM server, Liberty will often tune the number
  of active threads by decreasing and increasing by one.
  Every time a thread is deleted, DFHSJTH does not freemain
  the SJLRB storage. Over time, CICS may be short on
  storage (SOS).

Problem conclusion

• DFHSJTH has been changed to freemain SJLRB storage when a
  thread is deleted.  DFHSJDM has been changed to allocate the
  SJLRB and SJLLB subpools in CICS key instead of USER key.
