    Is it normal for a system to run like this?

    Code:
    Tasks: 238 total,  30 running, 201 sleeping,   0 stopped,   7 zombie
    Cpu(s): 97.3% us,  2.7% sy,  0.0% ni,  0.0% id,  0.0% wa,  0.0% hi,  0.0% si

    In trying to debug a bad update I noticed my system running slower than normal and e-mail taking more than 20 minutes to arrive. I am running on dual AMD64's with 2GB of ram. Let me know your thoughts.

    Thanks,
    Mel

    Don't have a solution, but doesn't look too good. You need more horse power for the spamassassin processes, but you don't have it. In the mean time more mails are arriving, requesting for even more cpu resources.

    Maybe stop the MTA (Postfix ?) temporary until all mail is scanned to fix this immediate problem? The fact that the MTA is not available should not lead to missing emails, as normal servers wild do retry's (up till 3-5 days). More permanent investigation should probably be done.

    Yes, the system was being bogged down by all the clamscan and spamassassin that was held up in the queue. It took about an hour to clear up after fixing my botched upgrade.

    Now the top looks like this:
