After updating to centos 4.3, I notice a failure in terminating 
irqbalance whenever i shutdown the system. Checking the services after 
the system reboot i see the error in irqbalance:
"irqbalance dead but subsys locked"
Can anyone tell me what irqbalance is and if it safe to disable it ? 
Why i dont see it in centos 4.2?
Thanks in advance.
