Graeme,
Thanks for the reply.
Looking in the MIB, I see the following definitions:
LvsServiceEntry ::= SEQUENCE {
lvsServiceNumber INTEGER,
lvsServiceSchedType OCTET STRING,
lvsServiceProto INTEGER,
lvsServiceAddr IpAddress,
lvsServicePort INTEGER,
lvsServiceFWMark INTEGER,
lvsServicePersistTimeout TimeInterval,
lvsServiceNumDests INTEGER,
lvsServiceStatsConns Counter32,
lvsServiceStatsInPkts Counter32,
lvsServiceStatsOutPkts Counter32,
lvsServiceStatsInBytes Counter64,
lvsServiceStatsOutBytes Counter64,
lvsServiceRateCps Gauge32,
lvsServiceRateInPPS Gauge32,
lvsServiceRateOutPPS Gauge32,
lvsServiceRateInBPS Gauge32,
lvsServiceRateOutBPS Gauge32
}
So, looks like that might be the problem; lvsServiceStatsConns is 32-bit.
I wonder if it's as simple as changing ASN_COUNTER to ASN_COUNTER64 in
the appropriate place in lvs.c ?

I think I'm polling at 5 min intervales.
