cactid is just rtgpoll (from rtg.sourceforge.net) with a few
customizations.  unfortunately, the copy is from an old codebase and
there are problems in the threading & snmp code from those days. even
more unfortunately, rtgpoll development seems to be hopelessly stalled
due in part to project mismanagement.

it's also much easier to debug problems with either the poller itself
or the devices being polled.

i'd use the php poller with cacti.
