Indeed
OVERRRRRRload especially Googlebot. I asked the ISP for more RAMs but they couldnt since we have reached our limit

I did some limitation and fine tuned the apache (web server) and mysqld (database) to solve memory leaks & any waste of resources. If you remember the forum used to die in the past but now not much. I did the cheap way by fine tuning but if it continued to die & affectin the performance then I have no other choice but the expensive one
That is hardware upgrade: RAMS & CPU
Anyways time will tell...
