I've moved to a new server which has more processing power and memory. Since moving my sites over I keep getting 502, 503 and 504 errors popping up for my websites. I increased the PHP limits and that made it a little better. But right now the PHP settings on the new server have to be higher than on the old one and I'm still getting downtime/errors across the two main websites. Attached are images of the old server settings (128/300/60/8) which were at default and the new server settings (300/120/120/16) which have had to be increased. So where do you look if a more powerful server with higher PHP settings keeps crashing the sites? Is there a display of scripts where you can toggle to see which ones are taking the longest to run?
