Как разобраться со стрейсом apache?

Помогите понять, куда копать. Стрейсил процесс apache и увидел такой цикл:

strace: [ Process PID=2496 runs in x32 mode. ]
strace: [ Process PID=2496 runs in 64 bit mode. ]

В чем может быть проблема ??? При всем при этом это создает нагрузку на MySQL, а СУБД в свою очередь на CPU.
