Made three Heapdumps, two shortly after starting the app and one when getting very slow. Since I don't know how to print them some
results here: Last-second: lava.lang.objt: Instances +7 , Size: +56, other differences smaller.
Last-first: lava.lang.object: Instances :-21 , Size: -186, int[]: Instances -126, size -625, com.sun.jna.memory Instances -623, size: -14952, java.lang.finalizer: instances: -631, size -20192
P.S.: The logic analyzer shows me that synchronization is not lost between the µC and the PC when close to the "stalling" condition.
Erel: May I mail it to you?
