[Devmon] Counter64 stat

[Aiello, S. \(G. C. consultant\) <ste...@ge...>]

Know of any issue when polling a counter64 stat ?  Still playing with my
BigIP, when I add the line to my oids file

sysTmTotal      : .1.3.6.1.4.1.3375.2.1.1.2.1.41.0      : leaf

and I run "./devmon -vvvv -f" I get:

Cannot restore overloading on HASH(0x8f69814) (package Math::BigInt) at
../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/thaw.al)
