A specific API query that my bot is trying to run is timing out. I've tried to run about 15 times and it reliably times out every time.
A sample response:
Request from [redacted] via cp1079 cp1079, Varnish XID 918790924

Note: if you run this query as a normal user, it will succeed. It only fails when logged in as a bot or administrator with the higher limits.

I see only four log entries for this request (specifically, for requests containing "Stift_Klosterneuburg_A3" in the URI) in the past 24 hours. Two indicate the same error as in T187759: API is returning 500 status code. One indicates that the query was being slow to execute. And one seems to be indicating that a 500 response was returned.
It's possible that for the other attempts the "too slow to execute" happened before it got to the point of exceeding memory usage, although I'd expect to see log entries for all those too.
