Obtain the fix for this APAR.

APAR status

Error description

• VSMGUARD crashes under time of heavy utilization. Recycling
  VSMGUARD results in bringing SMAPI down and requiring a recycle
  of the entire OpenStack compute node.
  

Local fix

• Restarting VSMGUARD recovers the system from the abend.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users operating with SMAPI could encounter   *
  *                 this issue.                                  *

  ****************************************************************
  Several different abends can happen when running on a system
  using SMAPI, which will prevail until SMAPI is restarted.
  

Problem conclusion

• The zhcp code and zthin-parts code will now attempt a SMAPI
  Response Recovery when the call to SMAPI returned a request ID;
  yet the next socket read failed with a connection problem
  (timeout, not connected, or refused). If the Response Recovery
  call then fails to find any socket data on the SMAPI queues,
  the call will fail. If the Response Recovery returns with RC 4,
  RS 4, or a connection problem, the Response Recovery will be
  retried a few additional times.
