Hi Otis, not really a problem because I have plenty of memory ;-) -Xmx25g -Xms25g -Xmn6g
I'm just interested into this. Can you report similar jumps within JVM with your monitoring at sematext? Actually I would assume to see jumps of 0.5GB or even 1GB, but 5GB? And what is the cause, a cache? And is there another option in JVM to give memory jumps a size?
