Uninterruptible processes increase

Hello Forum,

Our Virtual Appliances occasionnaly run into 70 LOAD making the gui almost unreachable, everything goes extremely slow and in pacemaker we get a clear indication the load is very high
In HTOP we noticed that this starts when a number off processes get state D = uninterruptible
Things escalate and everything becomes extremely slow. The only thing we can do is do a restart on the site.

The biggest problem is : we can not simulate this event, it just happens
The only thing we did was upgrade the firmware to 1.6.9 (higher upgrades are planned) but event started 24h after the upgrade

Has anybody encountered this ?

tuning tuning tuning is everything

If this ever happens to you, check your total number of hosts en services, do the math

Fast fix → uib site controle disable services/hosts and wait
