During the startup of the agent, below error message is displayed:
Cannot create IPC channel (No space left on device).
You might need to run "ipcrm -Q 0x41030130" to remove it if it already exists.
Running " ipcs -a |grep 0x4103 0130 " does not display this message queue
From a system trace, the agent is trying to create this message queue with key 0x41030130 and failed with error -1 ENOSPC (No space left on device)
disk space and swap space was not an issue
Quick solution is to reboot the Server.
Long term solution is to increase MSGMNI kernel parameter
