I have a server with a high average load when it's not doing much work see below:
I added an additional processor yesterday but it has not made any difference to the load averages.
I am using fail2ban and wonder if that would cause this problem?
free -h
shows:
total used free shared buffers cached
Mem: 1.1G 964M 150M 14M 147M 477M
-/+ buffers/cache: 339M 776M
Swap: 2.0G 6.3M 2.0G
Using ps awwlx --sort=vsz
. This shows processes sorted by virtual sizes I have included the bigest ones below:
