Informix HPL message 23203: Cannot Create Shared Memory Message Queue - error %d

Oninit® Troubleshooting Guidance

What it means

onpload could not create the shared-memory message queue it uses to pass messages between its processes. %d is the error from the failed system call.

Common causes

• The operating system's shared memory or System V IPC limits are exhausted.
• Leftover IPC objects from an earlier onpload run that crashed.
• The user lacks permission to create the IPC object.

What to do

• Look at ipcs for stale segments or queues belonging to the previous run and remove them if no onpload is running.
• Raise the kernel IPC limits if needed.
• Rerun the job.
