Lots of trouble on lizard isotesters: low on RAM?
Dear @sysadmin-team,
Since a few days, I see lots of unusual failures on lizard isotesters, which all suggest these machines are running low on memory.
Could this be related to the fact we started running icinga2 there a few days ago?
The FT is in the last few days preparing 4.16 so having a reliable CI infra at this particular point of time would be very helpful :)
