Hi
Analyzing Garbage Collection we have seen on minor collection that the
value after garbage collection is bigger then the one when it's
started. Before Garbage Collection we have about 200 MByte, after
Garbage Collection we see somewhat about 380 MByte. Why?
Who has seen this? How do explain that?
Thx,
Kurt

the value of what? free ram? You SHOULD see an increase. That is
what GC is for. Obviously you must mean something else.
