OA49823: ROUTE COMMAND TO MORE THAN ONE SYSTEM STOPS WORKING - MESSAGE IEE421I ISSUED INDICATING NO RESPONSE RECEIVED FROM SYSTEMS

APAR status

• Closed as unreproducible in next release.

Error description

• A ROUTE command targetting more than one system issued message
  IEE421I indicating that NO RESPONSE RECEIVED FROM THE FOLLOWING
  SYSTEM(S)  and the list was all systems the command was ROUTED
  to.  A review of the SYSLOGs showed that the command had been
  sent to each system, and each system processed the command and
  issued the resonse, however, the responses did not get
  aggregated into the IEE421I.
  A display of the *ROUTEnn console showed that queuing to it was
  SUSPENDED due to MEMORY LIMIT reached.  We were able to
  determine that there had been a ROUTE *ALL,F CATALOG,CLOSE
  command issued, which generated many IEC331I messages, which
  were all targetted to the *ROUTEnn console.  This flood of
  messages to this console, along with going to SYSLOG and OPERLOG
  (also EMCS consoles in the CONSOLE message dataspace), resulted
  in the MEMORY LIMIT being reached.  At the time of the dump, the
  SYSLOG, OPERLOG, and DIDOCS EMCS consoles were all operating
  properly, and only the *ROUTEnn console was suspended.  An IPL
  was necessary to recover the *ROUTEnn console in order to
  aggregate command responses.

Local fix

• The ROUTE command continues to work, however, the responses do
  not get aggregated into the IEE421I.  The only way to recover
  this situation is an IPL.
