Proxy AJP apache 2.4 timeout

[Simon]

Hi, for some reason Jira does not load completely and stops in the middle. The apache error:

[Thu Oct 15 11:09:19.951028 2020] [proxy:error] [pid 3316270] (111)Connection refused: AH00957: AJP: attempt to connect to 127.0.0.1:8009 (localhost) failed
[Thu Oct 15 11:09:19.951145 2020] [proxy_ajp:error] [pid 3316270] [client IP:56631] AH00896: failed to make connection to backend: localhost, referer: http://jira.domain.com/startup.jsp?returnTo=/default.jsp

Vhost

ProxyRequests Off
ProxyPreserveHost Off
ProxyPass / ajp://localhost:8009/ retry=0 connectiontimeout=10000 timeout=10000 nocanon Keepalive=On
ProxyPassReverse / ajp://localhost:8009/

server.xml

<Connector port="8009" URIEncoding="UTF-8" enableLookups="false" secretRequired="false" connectionTimeout="100000" protocol="AJP/1.3"/>

The CPU is 100% when loading

Thanks

Hi Simon,

it will be hard to nearly impossible to pinpoint the root cause by the log file snippets. Although the maxed out CPU worries me the most currently there is no sign where the trouble might originate.

Have you had by any chance the time to read through the troubleshooting section?

It should give a first idea where to start from. Screening logfiles will be crucial - as well as checking the server as such.

I am afraid, but at the moment it could be literally "anything".

In case you can provide some more details someone from Community is more likely to say something by technical by means to your issue.

Cheers,
Daniel
