Changes in load
Something has changed: where over a day there was a continuous change in CPU usage, it changed to peak every 90 minutes or so; drop significantly and gradually increase to about 80% – an drop again:
.No idea yest where this comes from….
Changing the execution time of the PHP processes didn’t help much. But before I could add something, the blog didn’t show up; that is: it started displaying but broke halfway. So I started the admin pages and found that there were quite a lot of requests that succeeded, others stalled, or simply broke: network connections dropped, processes exited…So there is another possible cause: the throttle; intended to prevent overload, it now bites back: PHPWASD does start a number of worker processes and I already noticed that this version of wWordpress puts quite a load on the resources. So a max of 5 may be too low.
So I’ll increase that.
