I haven't had the problem since I adjusted quite a few apache, PHP, and mysql settings. I also installed APC (Alternative PHP Cache), which seems to have helped quite a bit.
If it might help I would be happy to let you know what settings I'm using now. Of course it depends on what you have for a system.
thanks for help, I found problem... it was two guestbooks that wasnt secure, so heckers was abusing them, I delete those and now I am back on normal. I also make some modifications to mysql and install monit and munin those are great. Thanks again
