Hello, I have an issue, not the first time it happens.
The server start responding very slow (all services), logged in I run an uptime and get really HIGH cpu usage values, like this:
[[email protected] ~]# uptime
18:38:27 up 33 days, 22:42, 1 user, load average: 86.75, 81.58, 61.51
growing up minute a minute...
As soon as I see this, I run a top to find the preccess causing this high CPU usage, and for sorprise I can't see any process consuming lot of CPU and the CPU usage from top is normal:
top - 18:38:25 up 33 days, 22:42, 1 user, load average: 86.75, 81.58, 61.51
