[users@httpd] FW: TimeOut expired | Multiple Balancers using multiple workers | Apache 2.2.17
We identified the root-cause:
- due to the same "BalancerMembers" (incl. route-names) for
"fs4_javaclient_over_http"
and "fs4_webclient_over_http", requests that are routed to
"fs4_webclient_over_http"
do take the timeout of 90 seconds of "fs4_javaclient_over_http".
So, it seems to be the only solution to really separate both by specifying
unique
BalancerMembers (using unique "route"-names).
The consequence: the tomcat configuration has to be adapted as well.
Do you agree?

Subject: [users@httpd] TimeOut expired | Multiple Balancers using multiple
workers | Apache 2.2.17
Hi group,
we have the following topology up and running:
Apache2 (works as load-balancer)
| |
Tomcat1Tomcat2
(rb-wcmstc1) (rb-wcmstc2)
using the following TWO balancers named "fs4_javaclient_over_http" and
"fs4_webclient_over_http"
specifying DIFFERENT TIMEOUT VALUES with "90" and "660" seconds:
BalancerMember ajp://rb-wcmstc1.xx.x.xxx:8009 loadfactor=100 retry=10
route=rb-wcmstc1 connectiontimeout=5 timeout=90
BalancerMember ajp://rb-wcmstc2.xx.x.xxx:8009 loadfactor=100 retry=10
route=rb-wcmstc2 connectiontimeout=5 timeout=90
ProxySet stickysession=JSESSIONID|jsessionid
ProxySet lbmethod=byrequests
ProxySet scolonpathdelim=On
ProxySet nofailover=Off
BalancerMember ajp://rb-wcmstc1.xx.x.xxx:8009 loadfactor=100 retry=10
route=rb-wcmstc1 connectiontimeout=5 timeout=660
BalancerMember ajp://rb-wcmstc2.xx.x.xxx:8009 loadfactor=100 retry=10
route=rb-wcmstc2 connectiontimeout=5 timeout=660
ProxySet stickysession=JSESSIONID|jsessionid
ProxySet lbmethod=byrequests
ProxySet scolonpathdelim=On
ProxySet nofailover=Off
Incoming requests for ONE TYPE of HTTP-Client are using the
"fs4_javaclient_over_http" balancer via:
RewriteCond %{REQUEST_URI} ^/servlet/ClientIO/* [NC]
RewriteRule ^/(.*) balancer://fs4_javaclient_over_http/$1 [proxy,last]
the other HTTP-CLIENT is using "fs4_webclient_over_http":
RewriteCond %{REQUEST_URI} !^/servlet/ClientIO/* [NC]
RewriteCond %{REQUEST_URI} !^/index.html
RewriteRule ^/(.*) balancer://fs4_webclient_over_http/$1 [proxy,last]
This is done to separate connection losts for long running requests. Formerly,
when one Client provoked
a request that took longer than the configured "timeout" value, both clients
lost their connection due to a Tomcat switch.
THE PROBLEM
- in Apache2 "error_log" we see that a TIMEOUT HAS EXPIRED:
[Wed Feb 16 19:43:08 2011] [error] (70007)The timeout specified has expired:
ajp_ilink_receive() can't receive header
This leads to a switching of the Tomcat from "rb-wcmstc1" to "rb-wcmstc2"
or vice versa only for requests that run over the "fs4_webclient_over_http"
balancer.
But It's really strange, that we can't find any request that takes longer
than the configured TIMEOUT parameter of "660" seconds (see config
above) within the Apache2 ACCESS-Log. What we can see is: there
are long running requests - but they do not reach the value of 660 seconds.
When enabling "debug" LogLevel we see more details (see excerpt enclosed).
Our questions:
- is the configuration okay?
- which timeout is expired? (connectiontimeout?, replytimeout?, etc.)
- why does it happen?
- is it a Tomcat connection-problem?

I had ran into a case where we tweaked it real high on a dev box (5m seconds) and we had a process, though somewhat idle, that never finished. The connection was disconnected but the thread didn't go away. We only discovered it when all threads were in use. In our case it was a web service that accepted some data and was supposed to do processing, which should have finished in a few seconds. Just a thought.
[users@httpd] ResinConfigServer and CauchoHost
Hi , i have installed Apache2.2.8 on Solaris 10 . In httpd.conf i had set - ResinConfigServer 203.165.30.40 28064 but i was not able to access the UI deployed in resin. Response was 503. but when i replaced ResinConfigServer by CauchoHost , it worked fine. i came to know ResinConfigServer is alternative to CauchoHost. so my question is - is there any platform specific difference between ResinConfigServer and CauchoHost? Thanks, Vivek

[users@httpd] relay or forward or route or redirect HTTP requests
Hi there. Is it possible and if yes with what technique/program to achieve the following: Situation: I have a network with a public accessible webserver on 'WAN-a' Here runs an Apache server (CentOS Linux). This server has a second interface 'LAN-b' Further down on 'LAN-b' is a Cisco PABX (telephone server) that is managed via an internal webserver (tomcat). Goal: The setup the apache server (or other server/program/...) on 'WAN-a' in such a way that requests from external users are handled/passed/routed via the internal 'LAN-b' to the webinterface of the PABX and vice versa. I'm not sure if this is called routing, relaying, proxy, or So I don't know in what direction I need to search and investigate for a solution. Any tips guiding/leading in the right direction are very welcome. Thanks Jan-Willem Speckmann ** The information in this email is confidential and may be privileged.
