Tomcat – (103) Software caused connection abort: proxy: pass request body failed

apache-2.4javatomcat

The following errors are being logged in our proxy Apache logs while processing the request with Tomcat Server:

(103)Software caused connection abort: proxy: pass request body failed  
proxy: pass request body failed

We've a Apache reverse proxy which serves the request for the client from our Tomcat Server. Sometimes, the request from the proxy returns 502 with the above error.
There are no error logs in Tomcat Server Logs correlated with the above errors in Proxy. Also, the request didn't timeout since some of the requests response time is 1 sec and our default timeout is 120 sec.

We've added ProxyBadHeader Ignore to our httpd configuration [Ref: 502 Proxy Error / Uploading from Apache (mod_proxy) to Tomcat 7] and still didn't see any errors in our Tomcat logs.

Have anyone seen this issue earlier?

I came across this same error recently. Our solution was to add:

SSLProxyProtocol all -SSLv2 -SSLv3

This matches our SSLProtocol parameter in our ssl.conf file. We also had Tomcat setup to disable SSLv3 as well.

Update

Have you tried monitoring the number of busy threads in Tomcat? Perhaps Apache is not releasing them properly.

First attempt, not working

Reverse name lookups for DOMAIN?

I'm going to shamelessly plug my stack overflow answer. Note that it allows you to use localhost instead of DOMAIN.

<VirtualHost *:80>
  ServerName public.server.name

  ProxyRequests Off
  ProxyPreserveHost On

  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:8180/
  ProxyPassReverse / http://localhost:8180/
</VirtualHost>

Tomcat – Reading .htaccess and Tomcat

.htaccess is meaningful to httpd only. Once a request is passed over to Tomcat, it is under rules of Tomcat's realm. You may handle a part of Apache's namespace to Tomcat though.
