thanks @r.sander, I think you may be right. There may be a HAPROXY setting that would fix this as well.
Seems wierd, but the server RAM idles at 2% usage while throwing this 700 - 900% CRIT on committed memory. Since it’s in a kvm, RAM will expand as required anyhow so I just wrote a rule to Warn:900%:Crit:1000%.
Strangest rule I’ve ever written though.
