IBM i console displaying COMM655MW

The IBM i console is frozen and displaying COMM655MW

Resolution

If the IBM i VM is still running and you can access the OS via TELNET or SSH, the following procedure may help restore access to the console:

1. Close out any open SRA sessions to the VM
2. Connect to the VM via SSH or TELNET
3. Run WRKACTJOB to display active jobs, and look for jobs beginning with DSP, such as DSP01
4. Run ENDJOB JOB(jobid) where jobid is the job identified in the previous step
5. Open a new SRA session to the LPAR and attempt to log in

If this behavior is seen on a regular basis, the following system values may need to be checked:

QINACTITV - The Inactive Job Time-Out Interval (QINACTITV) system value specifies in minutes how long the system allows a job to be inactive before taking action.

QINACTMSGQ - The Inactive Job Time-Out Message Queue (QINACTMSGQ) system value specifies what action the system takes when the inactive job time-out interval for a job has been reached.

Run the following commands to check these values

- wrksysval sysval(qinactitv)

- wrksysval sysval(qinactmsgq)

If this does not recover your IBM i console, please contact Skytap Support.
