Hey anyone upgraded to debian7 and noticed interrupts raised like 10x times? At first I though it server specific issue, but when I upgraded completely different hardware and noticed same thing even w/o booting into new kernel. So we had at one server about 160 and now 1700, and other server 280 now 1800. Also context switches increased 5-6 times from 500 to 3,5K now.
Nikolay,
I don't think it's related to wheezy per se; I have a jump from 10k to 15-18k context switches and from 7k to 15k interrupts on a machine, but the jump happened at the beginning of week 16, I only upgraded this to wheezy yesterday (this is the Observium host).
On a non-Observium host, I don't see a rise in interrupts nor context switches.

Well I'm not saying its debian specific. Its package specific for sure, and there isn't much to choice from snmpd isn't changed, only php and mysql get new version, which is related to observium. Probably python also involved as I didn't test with single poller but using poller-wrapper.
