Interrupts problems


My machine is a Unixware 7.1.3 is a files server, and I had never problem with that machine, but since two days, the machine presents slows problems, i think that the problem is te device interrupts, I had checked all and I dont found it any problem.

Any idea?

Thanks, (sorry my english is too poor)

Any idea?
