Memory leak in 2.0b4

Hi All,

Seems to be a memory leak in Nagios 2.0b4.

I've just upgraded my 6 Nagios servers to 2.0b4 (5 are distributed, one is
a central Nagios server).  Was previously using 2.0b2.

All 6 of them are exhibiting identical problems.

I restart Nagios once every 24 hours.

With 2.0b4: Within 24 hours, memory went from 80% free to 40% free, and
swap from 512mb free to around 200mb free.

With 2.0b2: Within 24 hours, Memory drops about 10%, swap is untouched.

Additionally 2 of my distributed servers crashed stone cold.

I know my servers are losing memory and swap because I graph these metrics
(data polled every 5 minutes).

Is this a known issue?  Is there any info I can supply to help developers
troubleshoot this?

Needless to say I've downgraded back to 2.0b2 in the interim.

Cheers
Alex.
