We have multiple xymon servers running with uptimes ranging from weeks 
to months. One of them is running sinds june 2015!

If there is a memory increase, it's in xymon_rrd.
xymon_rrd uses 3.054.896K on that server that's running since 2015.

I sometimes kill all xymon_rrd processes if we are getting low on memory.
