IPC (inter-process communication) resources are messages, shared memory, semaphores, and so on, that are used for sharing information between multiple processes and threads.

Applicable versions and levels
Solaris versions: 10.1 or later

Action 1
Cause
This error occurs if unable to collect IPC resources.
How to check
If IPC resources could not be collected, perform the following procedure to check which resources were not collected:
Display the status of the IPC resources.
/opt/systemwalker/bin/mpipcso
Check the execution result.
The IPC resources that could not be collected are displayed in the following portion of the execution result.
10.1:
Status of undeletion IPC from <stopping Systemwalker OperationMGR> T ID KEY DATE TIME PID CMD
11.0:
Status of undeletion IPC from <stopping Systemwalker Operation Manager> T ID KEY DATE TIME PID CMD
T: Type (m: shared memory, q: message queue, s: semaphore)
ID: ID
KEY: Key
DATE: Date of acquisition
TIME: Time of acquisition
PID: Process ID
CMD: Process name
Use a system command (ipcrm) to delete the IPC resources that were not collected previously.
Action method
Collect shared memory.
ipcrm -m <shmid>
Where <shmid> is the ID of the shared memory to be collected.
Collect message queues.
ipcrm -q <msqid>
Where <msqid> is the ID of the message queue to be collected.
Collect semaphores.
ipcrm -s <semid>
Where <semid> is the ID of the semaphore to be collected.

Action 2
Cause
If the error occurred in a cluster system, did you execute the service/daemon termination command (poperationmgr) without stopping the Systemwalker Operation Manager daemon registered in the cluster system?
An error message is output if you execute the daemon stop command (poperationmgr) without stopping the Systemwalker Operation Manager daemon registered in the cluster system.
Action method
No action is required to address this cause.
