memory graph so far:
looking very good!!!
@r1 our complete setup:
[FreeNAS NFS] <----shared-storage----> [Pool of 2 servers (xen22 + xen23)] ----XAPI---> [XO from sources] -----remote----> [FreeNAS NFS]
All [servers] are real hardware servers, no VMs involved.
Same chain of servers for xen19, execpt there are more pool members (and VMs).
@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"?
