@stormi I'm not complete sure if I did the iso upgrade or not...
But it's a good idea to reinstall the poolmaster from scratch...

Good news from the kernel-alt (server xen19): No RAM leaks so far
@stormi on server xen19 I think so, on server xen22 I'm not sure
I looked more close on my memory graphs and saw, that the memory baseline increases every night:
"bump" every day:
closer look in week 53:
Dez 31. - Jan 01.
Our Backups run from 18.00 till 3 or 4 in the morning (including coalesce).
--> maybe the heavy IO load leads to memory leaks "somewhere"?
@r1 yes, ever line "installed" in yum.log is an Upgrade from XCP-ng.
Problems started with XCP-ng 8.x
@r1 in general we do not restart many of our VMs, its all very static, only manual operated
xen19 is now rebootet (we need it in production) with kernel-alt - highest id is currently 4
xen22 (pool master of another affected pool) - highest id is curently 30
memory graphs of xen22

I noticed in my monitoring graphs, that since we have this issue, the SWAP is not used like before the issue:
We also have an issue with growing control domain memory:
Today I install the alternate kernel on one of our poolmaster to see if that resolves our issue.
@olivierlambert I just hit the compile button and massaged the github a bit Nothing of which I could be proud of...
