  | Comment1          :- Socket Connect Error
  
  MQ listener fails to start although the MQ queue manager can
  start.
  
  This problem is a result of changes in HP Non Stop Server
  SPRs T9050J01-AWT and T9050H02-AWS, which were included in
  J06.14/H06.25 respectively.

Local fix

• LOCAL FIX
  
  Set the environment variable "AMQ_NO_LISTENER_CHK=1" for OSS
  command line listeners.  For listeners running in PATHWAY, set
  an ENV value of AMQ_NO_LISTENER_CHK=1 in the listener
  serverclass.
  

Problem summary

• Due to change in layout of OSS PIDS in T9050 J01 AWT and
  T9050 H02 AWS, information returned from PROCESS_GETINFOLIST_ is
  incorrectly handled by remote library code used by
  the listener. These SPRs were part of the H06.25 and J06.14
  RVUs, but can also be installed on H06.24 and J06.13.
  

Problem conclusion

• Remote code changed to no longer expect OSS PID > 65537, but
  instead to specifically search only for OSS processes in
  PROCESS_GETINFOLIST_ call
  

Temporary fix

• For listeners, define the following environment variable.
  AMQ_NO_LISTENER_CHK=1. For command line listeners, this should
  be exported in the environment, for PATHWAY listeners, this
  value should be set for the serverclass. If the problem is
  encountered with endmqlsr, the listener can be terminated
  using kill -9.  Note that PATHWAY listeners are terminated whe n
  the serverclass is stopped, or the queue manager is ended.
