You shouldn't have near that many tasks running with just 100 uniques / day. Looks like maybe one of your httpd processes is hung up. Restart httpd and it'll probably get better.

 

Sorry, 1000 UV / Day

Its only in my Primetime from 18-21 hour so bad. Other time, when i get little traffic i have a load of 0 and ~ 80 sleepin and 0-1 active tasks.

I have now restart httpd but after restart the load goes high but now is my primetime
