Re: [Hawkular-dev] Memory-usage of Hawkular-services

Can you try doing a full-gc right before compression start and right after end to and measure the heap usage at those points (before start and at end before gc) so that we get an idea how much memory the compression really takes? I started a 0.16 h-services at ~ 10:35, let it run until 11:13 (first compression happened at 11) then added 25 feeds - one every 2 minutes. The compression at 1pm went well, but the graph certainly shows a much increased need for heap during that time.  We may perhaps try to spread out the compression over more time and thus trade time for memory to get rid of this large memory usage peak. After the next crash, I will try to run with external DB for Inventory to see how much this contributes to the issue here.
