Since about 10.00pm last night we have been getting load spikes on our website server. They last around 5 minutes and are reoccurring each hour. They dont seem to be in pattern like something is running every time.
I have checked the current running processes, also checked CPU and RAM usage.
They all seem normal.
I have also monitored the processes via ssh while the spike was taking place and the CPU % does not go above 20 and theres 50% RAM available. Also no sign of any specific process hogging the server.
