I have a SCO UNIX Open Server 5.0.7 system that had been running fine for years
however it started panicking with the error too many queued CPU interrupts.
after the 1st time it waited a couple months until it did it again, as time went on it got more frequent. now it is doing it a couple times a week.
I found a knowledge base article on the SCO web site that addressed it and said to adjust MAXACPUS, I have cranked that up to their max and still no good.
I am not an expert on SCO, just know enough to be dangerous. to the best of my knowledge the system is fully patched.
the system is an HP ML570 g4, 4 dual core CPU,s, 4gig memory, p600 controller card.
don't know now if I am looking at a software or hardware issue. if hardware what piece?

any ideas anyone?

thanks in advance
Tom
