when you specify the connection to mysql, are you including the 'autoreconnect=true' parameter? If not, the connections will be closed by mysql after (I think) 8 hrs.
I'm not sure why everyne's caught up in database connection code. This is a Coyote connector exception -- which is the HTTP/1.1 protocol connector. It allows you to connect directly to Tomcat using a browser, instead of going through Apache.
Usually the "Broken Pipe" means the the client hung up before listening for all the data. That could mean pressing the STOP button on the browser, following another link before the page fully loads, or pressing the back button.
I wouldn't worry too much about it, unless your users are somehow being affected.

Subject: problem with mod_jk 1.2: error in action code
Hello,
I've got problems with a tomcat web application, that establishes a connection pool to a database (mysql). This connection pool is lost after an unspecified period of time the system wasn't used (f.e. 8 houres).
I think the problem is due to the mod_jk connector between apache and tomcat.
The web application is accessible over apache 1.3.27, that connects to tomcat 4.1.27 via jk connector mod_jk 1.2.25.
The exception I got in catalina.out is:
10.03.2004 15:59:58 org.apache.jk.server.JkCoyoteHandler action
SCHWERWIEGEND: Error in action code

The HTTP connector defined in tomcats server.xml is:
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8009" minProcessors="5" maxProcessors="75" enableLookups="false" redirectPort="8443" acceptCount="10" debug="5" connectionTimeout="0" useURIValidationHack="false" protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"
scheme="http"
secure="false" />
The log in mod_jk.log shows the following:
[Wed Mar 10 15:59:58 2004] [jk_ajp_common.c (1052)]: ERROR sending data to client. Connection aborted or network problems [Wed Mar 10 15:59:58 2004] [jk_ajp_common.c (1303)]: ERROR: Client connection aborted or network problems
Here is the summary of my environment options: - tomcat 4.1.27 - apache 1.3.27 - mod_jk 1.2.25 - Suse Linux 7.2 - Java 2 RE Standard Edition, Version 1.4.1 (build Blackdown-1.4.1-01)
My special problem is, that I'm not able to reproduce the error, it occurs after an unspecified period of time. I found nothing related to this problem. Any ideas?
Thanks in advance M.Goerlich
