High IRQ/Soft-IRQ - Need help, please!

Dear all,

my beloved ;) KVM became unresponsive this night for several minutes. The Munin graph shows a spike in IRQ/Soft-IRQ during that time frame:


I already did some reading but still have not found the answer to the question: What can I do to avoid something like this happening again? Is there anything I can tweak on the server (CentOS 5.8, nginx, php-fpm, apc, running a gallery site) or is this a problem originating from the KVM node?

The Kernel version is 2.6.18-308.4.1.el5.

I am really at my wit's end and would appreciate your help/feedback a lot!
Thank you in advance & kind regards
