    Have a look @ your Queries. I think you should optimize them.

      Yes you are right and i know that the queries need to be optimized but without having changed the code for months. only the last few days i face this problem so hard.

      is there any other reason about this?

        Its hard to say.
        A "show full processlist" should give more informations:-)

          Yes you are right again but when now i start to run the site (enabling the first page) the server is unreachable in few seconds....

          so now a i can not provide sth like that...
