All, I am having issues after configuring 3rd Q manager on a solaris 8 sever, sometimes SDR channel would not come up, status remains in initializing state. sometimes runmqsc <Qmanager name> takes back to the solaris prompt. If I am able to shutdown one of the Qmanager, then other two Qmanagers would continue to function properly. otherwise use ipcrm to remove mqm objects & start Qmanagers.
Looking at the log file, system complains about " no space left on the device". I increased semop value from 100 to 128 few days back.
Any suggestion what parameter need to be changed/increased to resolve this issue?
