There might be a memory leak with HLS components.Try disable that.

hy,

i habe changed

hls {
enabled off;

to off and restart it, no changes in ram usage

[tausday]

Hy I have test it from 5.0 over 6.0 to developer releases all the same

If I refresh the summary/dashboard often I can see a ram usage increase faster than I do nothing.

Maybe some log files in cache or other thinks in cache?

Any ideas. I don't can be the first who find out it :)
