I’ve done a bit of digging, but can’t find a solution so far - I’m running into a intermittent 502 bad gateway when using an ajax plugin - ajax load more.

One potential solution I have come across is to increase the php\_max\_execution\_time

So the question is - what could be the root cause of the problem in the first place, and would increasing the php\_max\_execution\_time be the best solution, and if so what would an acceptable setting be?!

The intermittent nature of the issue points to something like a memory issue, but I’d rather make sure it’s not just a sticking plaster to a bigger problem.

I ended up increasing the fast cgi buffers which resolved the issue.
