Gah. It is run-debuginfod-webapi-concurrency.sh again with
error_count{libmicrohttpd="Server reached connection limit.
Closing inbound connection.\n"} 9

I guess 100 parallel lookups really is too much. I am going to lower
it to 64.

Cheers,

Mark

Subject: [PATCH] tests: Lower parallel lookups in
 run-debuginfod-webapi-concurrency.sh

With 100 parallel lookups we sometimes see:
Server reached connection limit. Closing inbound connection.

Lower parallel lookups to 64
