I think the bug report makes perfectly sense - snmpd is flooding my logfiles
with this message!
The kernel can hardly be blamed that it reports more than an uptime >= 2^32 if
the system really idled that long. So if snmpd wants to squeeze the value into
2^32 bits it should simply do a "modulo 2^32" like it does for 32bit network
interface counters as well.
Counters of a specific bit site are supposed to wrap around somewhen. That's an
inherent problem of Counters and all clients should be able to deal with that
so there is no reason for a warning, or?
