Bug ID: 57849
Summary: Service Temporarily Unavailable
Product: Apache httpd-2
Version: 2.2.15
Hardware: PC
OS: HP-UX
Status: NEW
Severity: normal
Priority: P2
Component: mod_proxy
Assignee: [email protected]
Reporter: [email protected]
Hi Apache,
Firstly Thank You For Providing an Opportunity for raising bugs and mailing
list.
My Issue goes like below,
When apache is trying to connect to backend server (in my case) Tomcat at port
1188, Sometimes I hit "Service temporarily unavailable" issue.
When "Service temporarily unavailable" issue is hit, we are seeing following
below message in error_log
[Mon Apr 20 14:45:06 2015] [error] (239)Connection refused: proxy: HTTPS:
attempt to connect to 127.0.0.1:1188 (localhost) failed
[Mon Apr 20 14:45:06 2015] [error] ap_proxy_connect_backend disabling worker
for (localhost)
By the error message it seems that when ever apache is trying to connect to
tomcat at port 1188 and if there is no service running at this port then this
issue is hit.
In google, I observed to add retry=0 at PassProxy to avoid this error. I did
the same changes but still I am facing same issue
ProxyPass /sgmgr https://localhost:1188/sgmgr retry=0
Below are my questions,
1. Who is printing “Service Temp Unavailable” message ? Is it possible to
change the error message “Service Temp Unavailable” to some other meaning full
sentence so that user will not be confused with this error. Since this error is
temporary, can we mention workaround like press F5
2. Is there any other configuration property to avoid this error like retry=0.
3. In general how we can avoid "service temporarily unavailable" issue
4. Is there any new version of apache where this issue has been fixed
Thanks,
Sandeep
