Some reasons why this might happen: Tomcat may have crashed The web application did not respond in time and the request from Apache timed out The Tomcat threads are timing out A network device is blocking the request, perhaps as some sort of connection timeout or DoS attack prevention system If the problem is related to timeout settings, you may be able to resolve it by investigating the following: ProxyTimeout directive of Apache's mod_proxy Connector config of Apache Tomcat Your network device's manual share|improve this answer answered Jan 29 '14 at 2:18 rmeakins 899611 add a comment| up vote 16 down vote Add this into your httpd.conf file Timeout 2400 ProxyTimeout 2400 ProxyBadHeader Ignore share|improve this answer edited Sep 6 at 16:52 Ian Hunter 3,49973559

Error 502 Tomcat http://stackoverflow.com/questions/169453/bad-gateway-502-error-with-apache-mod-proxy-and-tomcat has plenty of threads, so it's not thread-constrained. We're pushing 2400 users via JMeter against the app. All the boxes are sitting inside our firewall on a fast unloaded network, so there shouldn't be any network problems. Anyone have any suggestions for things to look at or try? We're heading to tcpdump next. UPDATE 10/21/08: Still haven't figured this out. Seeing only a very small number of these under load.

Navapara Mar 12 '15 at 5:27 add a comment| 7 Answers 7 active oldest votes up vote 32 down vote Just to add some specific settings, I had a similar setup (with Apache 2.0.63 reverse proxying onto Tomcat 5.0.27). For certain URLs the Tomcat server could take perhaps 20 minutes to return a page. I ended up modifying the following settings in the Apache configuration file to prevent it from timing out with its proxy operation (with a large over-spill factor in case Tomcat took longer to return a page):

I'm trying to install GitLab on my server, and I have this error when trying to reach the web page of gitlab :
Proxy Error
The proxy server received an invalid response from an upstream server. The proxy server could not handle the request GET /users/sign_in.
Reason: Error reading from remote server
But, all the componants of gitlab are running normally, and the return of
sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
showed no errors. (Unicorn is working)
So I think the problem come from Apache, but after tons of attemps, I could not figured out where the problem is.. So there is my apache conf for gitlab :
`
ServerName gitlab.domain.com
ServerSignature Off
ProxyPreserveHost On
ProxyPass / http://www.domain.fr:8080/ retry=1 acquire=3000 timeout=600 Keepalive=On
AllowEncodedSlashes NoDecode
