Mod_Proxy 502-Proxy Error intermittently

I am using Apache 2.2.16 and Tomcat 7.0.16. I have 3 instances of Tomcat that runs 3 different war files. To get around the request, I configured httpd using mod_proxy.

3 Tomcat instances work in 8080, 8090, 8099. find the httpd configuration below

ProxyPass /bor `http://localhost:8080/bor/ ProxyPass /borcafews/ `http://localhost:8090/borcafews/ ProxyPass /borechws/ `http://localhost:8099/borechws/

With interruptions, I received a 502 proxy error in 8090 and 8099. Therefore, I set the following variables in httpd.conf

 <Location /borcafews/> SetEnv force-proxy-request-1.0 1 SetEnv proxy-nokeepalive 1 </Location>`

After configuring this configuration, borcafews did not produce any proxy errors, but for borechws with a 502-Proxy error, the error is interrupted.

proxy: Error reading from remote server returned by /borechws/services/bor (20014)Internal error: proxy: error reading status line from remote server localhost:8099

Please help me solve this problem.

I'm not sure if this is a mistake in your Apache configuration: it is possible that your tomcat application will return the wrong answer.

Use tcpdump or tshark to capture traffic on the appropriate ports. This will confirm that your tomcat application returns valid HTTP responses.
