High Server Load

    I recently installed a Debian system and ISPConfig 3. I know that ISPConfig has nothing to do with the issue, but I know this is an active community. The problem that I am seeing is that I am seeing a constant server load of 2.00 with no CPU usage. It doesn't make sense to me. The machine has 4 GBs of ram and has a Core 2 Duo at 2.93 Ghz. Every machine that I have had this setup on beforehand has had a load of .01 or so. I would like to get the load down.

    Here is output of vmstat 1:

    Do you have munin installed? Does it also report a contant load average of 2.00? If that is the case, it seems to me as if something's wrong with top...

    Munin reports the same thing. It has an average of 2.00. There is absolutely no activity on the server though. I just want to track it down. I got a message from rkHunter telling me that something could be infected this morning.

    Is it possible that there is a process running that the root user cannot see?

    What is weird is that is was lower before yesterday. I installed awstats, roundcube, munin, and monit yesterday.

    Here are some graphs.

    What is also weird is that the yearly and daily graphs don't add up? They should be the same.

    Sorry I tried to reinstall Munin to see if that was an issue. The yearly graph was not updating like the other data. Maybe an issue with permissions and the process was hanging?

    Not sure on that, but I am waiting to see what the next run does.

    If you have any other ideas, it would be appreciated. Is there a way to reinstall the top command. From what I have found, it is a program named procps, but removing that removes a lot of other things, including ssh, which I need.

    Can you remove just a package and not the other packages that are no longer needed?

    Thanks.

    Please check your system with rkhunter and chkrootkit.
