Indeed.

Just rechecked. After 72 hours nagios still runs perfectly with an average 
service check latency of 0.3 seconds, max. 0.9 seconds.

Memory usage is perfectly "flat" now, with epn and perlcache it went from 
140 mb (whole system) to about 900 mb within 24h.

The average system load is a bit _lower_ than before, but some peaks 
higher than with epn/perlcache.

I'll try pure epn without perlcache first thing in january.
