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)

msgget(0x41030130, IPC_CREAT|0666

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
