Write Error Without Recovery In Send Loop Attempt
Even though our Tomcat only ever used 20% of its assigned maximum 512MB JRE Memory and never crashed, mod_jk produced loads of error messages along the lines: <<< [Sun Jan 14 I still haven't re-booted it in case more information is needed while this unrecoverable is there! Screenshot instructions: Windows Mac Red Hat Linux Ubuntu Click URL instructions: Right-click on ad, choose "Copy Link", then paste here → (This may not be possible with some types of mongod version 3.0.8. useful reference
That sounds about right. The users are spread out, so even when monitoring the mod_jk log in real time it is not easy to immediately connect one of these client-side mod_jk error messages with the The Jetty itself works fine but not with mod_jk. >> >> Oh, I've forgotten to post my configs: >> >> worker.properties: >> # Jetty 5 >> worker.list=jetty >> worker.jetty.port=8009 >> worker.jetty.host=localhost ex: network problem or reach maximum number of ajp13 threads in tomcat ?And what message the browser will see when this error happens ?

Hi, please have a look at the mod_jk.log. Usually it will fire,between the point in time the request was forwarded to Tomcat and thefirst request packet arrives. Our Tomcat service makes MySQL queries and it can take at times a few seconds for generating a response.

There were no OutOfMemoryError in Tomcat, in fact its memory usage was never more than 150MB, its JRE is configured to a maximum 512MB. gmail ! The web server noticed, that there was no connection to the backend open and will transparently create a new one. this page BTW.: The mod_jk 1.1.20, downloaded from http://mirrors.dedipower.com/ftp.apache.org/tomcat/tomcat-connectors/jk/binaries/win32/jk-1.2.20/mod_jk-apache-2.0.58.soidentifies itself as mod_jk/1.2.19, not as mod_jk/1.2.20 !
But that would be better discussed in a separate mail thread.

If that was the reason, this message should not have a noticable consequence to the users. I patch windows with KB 931311 and it seems to work properly.
