Broken pipe errors are something that we want to debug too. Our enviroment is: Tomcat 5.5.17, apache 2.2.3 mod_proxy_ajp
Sometimes we have a broken pipe too. Under heavy load, it happens more times, but our server keeps serving with no problems. Any ideas?

I am using Mac OS X 10.4.8, Tomcat 5.5.17, mod_jk 1.2.19, JavaSDK 5.0 and Apache 1.3.33 As far as I can consider, the config (<Connector>, httpd.conf, workers.properties) is very close to the defaults. The application itself seems to be okay. In fact the store is already online (even if driven by linux instead of mac os x) and serves a couple of hundred orders per day w/o worries. I just wanted to know why a simple ab -n2 -c2 http://q16.hq.martin.de/ makes a lot of noise (well one entry in this case) in my catalina.out <snip> 18.10.2006 20:17:37 org.apache.jk.core.MsgContext action WARNUNG: Error sending end packet java.net.SocketException: Broken pipe at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite (SocketOutputStream.java:92) at java.net.SocketOutputStream.write(SocketOutputStream.java: 136) at org.apache.jk.common.ChannelSocket.send (ChannelSocket.java:518) at org.apache.jk.common.JkInputStream.endMessage (JkInputStream.java:112) at org.apache.jk.core.MsgContext.action(MsgContext.java:293) at org.apache.coyote.Response.action(Response.java:182) at org.apache.coyote.Response.finish(Response.java:304) at org.apache.jk.server.JkCoyoteHandler.invoke (JkCoyoteHandler.java:204) at org.apache.jk.common.HandlerRequest.invoke (HandlerRequest.java:282) at org.apache.jk.common.ChannelSocket.invoke (ChannelSocket.java:754) at org.apache.jk.common.ChannelSocket.processConnection (ChannelSocket.java:684) at org.apache.jk.common.ChannelSocket$SocketConnection.runIt (ChannelSocket.java:876) at org.apache.tomcat.util.threads.ThreadPool $ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Thread.java:613) 18.10.2006 20:17:37 org.apache.jk.common.ChannelSocket processConnection WARNUNG: processCallbacks status 2 </snip> If I do an ab -n2 -c2 http://q16.hq.martin.de:8080/ the log file does not add such an entry. What's wrong here? To me it seems that the connection between Apache and Tomcat is somewhat broken or at least not correct configured?
