Hi @Timothy_Hall ,
No it is not causing any problem at this moment, only the fact that cpview shows the kernel usage increasing constantly and wanted to prevent any possible future problem when it reachs 100%, do you consider it can happen?
I looked up into sar files but only found the last seven days, pgpgout/s fault/s are relatively constant sinc Jun 29, only some spikes in times of policy install as you said.
Also saw the appliance is up 115 days now (with many failovers int the middle), it has happend many times before with an interval of 3-5 months to reach a porcentage >90, so i understand it should be a normal behavior? Some info below shows how swap and memory usage are bigger, but pgpgout/s also had a spike bigger than the last time i executed the commands so i think that is causing it, am i rigth?.
