Hi, We've got a number of 9.x machines - just setup a new 9.1-RELEASE-p4 amd64 system, put net-snmp on it (net-snmp-5.7.2_3) - and we're getting 'weird' results for some stats, e.g. UCD-SNMP-MIB::ssSysInterrupts.0 = INTEGER: 1145324516 interrupts/s UCD-SNMP-MIB::ssSwapIn.0 = INTEGER: 1145324612 kB UCD-SNMP-MIB::ssSwapOut.0 = INTEGER: 1145324593 kB That's an insane number of interrupts/second (systat shows 200-300 total) - also ssSwapIn.0 is 'The average amount of memory swapped out to disk, calculated over the last minute.'. The machine isn't swapping - and had 784k swapped out (according to Top) - it's lightly loaded (LA 0.02) w/3Gb memory 'free' and 3Gb inactive. Any idea where net-snmp is getting those figures from, or why? - Or better - how to fix? Thanks, -Karl
