[Bug 53233] New: Internal error: proxy: error reading status line
from remote server
https://issues.apache.org/bugzilla/show_bug.cgi?id=53233
Priority: P2
Bug ID: 53233
Assignee: bugs@httpd.apache.org
Summary: Internal error: proxy: error reading status line from
remote server
Severity: minor
Classification: Unclassified
Reporter: prakash22.s@tcs.com
Hardware: PC
Status: NEW
Version: 2.2.16
Component: mod_proxy_http
Product: Apache httpd-2
Created attachment 28781
--> https://issues.apache.org/bugzilla/attachment.cgi?id=28781&action=edit
Error
I'm Using Apache 2.2.16 and Tomcat 7.0.16. I have 3 Tomcat instance which
executes 3 war files. To bypass the proxy I have configured httpd with 3
workers.
3 Tomcat instances are running in 8080, 8090, 8099.
Intermittently I was getting 502 Proxy Error in 8090 and 8099 for all the POST
operations. So I have set the below variables in the httpd.conf
SetEnv force-proxy-request-1.0 1
SetEnv proxy-nokeepalive 1
After setting this configuration gradually the error rate got decreased but
still we are facing some issues.
When the request comes with HTTP/1.0 its working fine but when request comes in
HTTP/1.1 I am getting 502 Proxy Error at some times.
Please help me in resolving this issue.
Thanks,
Prakash S
