Hi,

I've recently upgraded my server from 5.4-STABLE to 6.0-RC1
and shortly after that i began to see these messages in my dmesg:

calcru: runtime went backwards from 1488581 usec to 1488580 usec for pid
65583 (mpsnmp)
calcru: runtime went backwards from 12674015 usec to 12674008 usec for
pid 98187 (mpsnmp)
calcru: runtime went backwards from 3507422 usec to 3507421 usec for pid
19660 (mpsnmp)
calcru: runtime went backwards from 4453368 usec to 4453367 usec for pid
28319 (mpsnmp)
calcru: runtime went backwards from 6126291 usec to 6126280 usec for pid
24134 (mpsnmp)

I've searched for this message, but haven't really found something
that explains what is going on.

The machine is dual Athlon MP with like i said 6.0-RC1 and stock SMP
kernel, and "mpsnmp" is a multithreaded snmp collector which stores
the data in RRD files. (i wrote it, maybe the problem is in it,
but i haven't seen these messages before).

So, is this something i should worry about?

Thanks,
--niki
