It's probably a timeout between the front end http server (apache?) and
the back end tomcat installation, related to mod_jk. IThe java
application takes too long to start generating an answer and the http
server (apache?) considers there is a problem and closes connection.
What you see in catalina.out is the result when the webapp starts to
write output and the connection has already been closed. This is just my
opinion, could be something else :)
En l'instant précis du 07/01/08 06:01, micro_learner s'exprimait en ces

I've volunteered to maintain a Java based application for a non-profit org.
Specs: Apache TomCat 4.1.24
Database : Mysql 4.X
Application : Java,VTL,Torgue and Turbine
The application used to gather reports works well for a small date range (
lesser time) and fails (not always) for bigger date range (more time , but
does not fail always.wks sometimes) with a
org.apache.jk.server.JkCoyoteHandler action
SEVERE: Error in action code
java.net.SocketException: Broken pipe on the Catalina.out.
The funny thing is that this same thing works on my Local machine (almost
same config but on Tomcat 5.3).
Also, even when the app. works fine the Catalina.out has this message (dont
know if it is benign)
