Hello
2 of 3 of my xen nodes ( dom0) died tonight because of out of memory error.
These servers are only running Xen and cluster suite packages.
I googled the error and everything point out to dom0-min-mem and grub
dom0_mem options
dom0-min-mem : I left it by default : (dom0-min-mem 256)
I read about on the internet but still do not understand this parameter
and if if should be =0 on servers
any advice ?
tx !
here are some info about one server :
