A few weeks ago I noticed that some of the wotaskd that were running were just in the top of memory consumers.
Actualy I have a wotaskd which has 42 instances running consuming ~285Mo (resident memory), it's a Wonder version
(06-01-2010 build for WO 5.3) running under Java 1.5 on an x86_32 Linux.
I noticed that Monitor consume memory too but less than wotaskd.
I had the idea of switching back to a vanilla version but profiling would be more helpful to understand why it's eating
so much memory.
