The host node would crash if the memory not enough.
For example,those services which running on the host node need 8G mem,but the host node has only 4G mem
Maybe it povide all memory for services running,as a result,the os slowly until crashed
Another case:A host node has many services with
Inactive status and some services with ‘Active’ status,and the memory is enough for
Active services,what would be happened if i actived those
I think rancher host maybe has
Resource Reserve Protocol to abvoid this situation ,but i can’t find it
