It seems i have a problem with pages . i don't know why,but when i add a few pages the server is crashing ( and i have a dedicated server,a powerful one,quad core,Intel(R) Xeon(R) CPU X3470 @ 2.93GHz with 12Gb of Ram) .same thing happens when i edited a page and push the update button . today is the same .
what could be wrong ? the server is recovering only after i restart it,also restart apache and mysql .i must say i have around 600 pages .
