I stopped the queue manager using the kill -9 PID command on the system. The problem is that when I tried to restart it, it's throwing the following error message on me.

AMQ6004: An error occurred during MQSeries initialization or ending.
I'm not able to recover from this error. Can anyone suggest me what I can do to restart the queue manager without any errors? Thanks, I need to fix this asap.

Vin,
a kill -9 is not a very polite way to stop a queue manager in the first place... Did it not come down with endmqm?
From the 'kill' I am guessing that you are dealing with a Unix box. It is very likely that your kill left some IPC resources behind.
Check out this: http://www.mqseries.net/phpBB/viewtopic.php?topic=264&forum=16
You probably have to modify it to work on your platform. Be aware that this removes all IPC resources for ALL queue managers on that box. So, if you have more than one, you better stop the others before you execute the command.
Good luck!
Stefan

PS. A machine reboot will solve the problem as well, if this doesn't work...

ps -ef | grep QMgr
and
end the processes in the following order:

amqpcsea - command server
amqhasmx - logger
amqharmx - log formatter
amqzllp0 - checkpoint processor
amqzlaa0 - queue manager agents
amqzfuma - qam process
amqzxma0 - process controller
amqrrmfa - repository process ( for clusters )

if you don't shut down a queue manager properly, you run the risk of MQ not tidying up o/s resouces such as semaphores and shared memory sets. This can result in a gradual degradation of system performance.
