Apache error log noise "Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1" on mwdebug1001
Open, MediumPublic

Description

Hello,

while testing changes at mwdebug1001, I noticed errors like "Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1" in Logstash (search query: https://logstash.wikimedia.org/goto/7f579ba81b5f33282f0c245578279554).

Example:

message
(111)Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:9001 (127.0.0.1) failed[proxy:error] [pid 26739:tid 139725939627776] (111)Connection refused: AH00957: FCGI: attempt to connect to 127.0.0.1:9001 (127.0.0.1) failed

type: apache2
channel: proxy
level: ERROR

Could this logspam be fixed? Thanks!

Does not affect production (debug server) and does not seem to affect MediaWiki error logging, either. It's unrelated noise from Apache, I think. Not sure what it means exactly.
