CPU usage problem

[hanuman.mumbai1947]

I am having same problem on my system. The Web Interface & My OS getting stuck after few days. I have checked CPU & Memory usage status.
By 'top' command. And see what I found....

1) CPU Usage is 80 to 90%.
2) 'amavisd' & 'java' service is using maximum CPU.

See The Terminal output by executing command 'top'

I am having same problem on my system. The Web Interface & My OS getting stuck after few days.

This is not the same problem mentioned above, that's a problem with MySQL. Do not add your posts to threads that have no relationship to your problem, I'll move this post to a new thread.

You need to look in the log files and see what's happening on your system. You also need to provide the specifications of your hardware. This looks like there's lots of mail in the queues, you need to find out why that's happening, check the log files. Have you made any changes to the anti-spam system or any other changes to Zimbra? Did you search the forums for similar problems?
