Hi
 
Ø       The 502 bad gateway error is
 
Sorry for  Hi-jacking up this Thread.
 
I too have some similar Issues with JBOSS /
Apache   LB process
 
I my case Apache is Displaying Bad Gateway  
[  http://wwww.application.com/aap1>
]
 
But  when the same page is being  direct
call  [ http://application:8081/aap1 ] internal direct hit to JBOSS server displays the  page
properly
 
 
Between 2 instance of JBOSS
4.2.1 and Apache 2.x we use mod_jk [ available from Apache Tomcat Connector Web
site ]

Clearly
those exceptions appear in jboss. Check if you have a stacktrace associated and
try to determine exactly which peer is involved when they appear.

Hi
Thanks  Alin
 
The 502 bad gateway error is  followed
by these error
 
·         java.net.SocketException: Connection reset
·         Blank request
·         java.net.SocketException: Unexpected end of file from server
 
Due you think all these are due to Jboss
server.

This
response suggest more that your jboss setup doesn't handle the load

then resumes normal operation after a while. We would appreciate any help and
thanks in advance.  Configuration Files would be shared if required.
