MQ explorer V9.1 hangs at startup. can someone provide any insights on how to fix the issue?
Sometimes it loads perfectly.
I have tried running with traces , but couldn’t see any errors.

The error when its hangs is as printed on from console is

Unhandled exception
Type=Segmentation error vmState=0x00000000
Windows_ExceptionCode=c0000139 J9Generic_Signal=00000004 


The end of service date for IBM MQ v9.1 was September 30, 2023. See:

You should un-install MQ Explorer v9.1, then download and install MQ Explorer v9.3 because you won’t get any support from IBM for a release that is no longer supported.

Update: January 9, 2024.

You need to provide more information (update your question).

  • What version/release of Windows are you using?
  • Are you running MQ Explorer on a PC/laptop or server?

  • Where did you install MQ Explorer?
  • Do you have anything in the MQ Explorer “dropins” folder/directory?
  • Do you have any other JDK or JRE in your PATH environment variable?
  • Are you running it on a PC/laptop with a very limited amount of memory?
