Re: Broken pipe exception

Fri, 19 Dec 2003 08:01:40 -0800

Hi,

the client is an applet and the browser hasn't been closed! Could it be the applet goes in timeout? Because after this error on server side the applet throws a an exception if we refresh the data!

could not send requests to server (root exception: java.io.IOException: First header field does not start with HTTP)

Howdy,
This is not related to your DB (at least, not likely to be related to
your DB).  It's probably your user closing the browser while the request
is still processing.  This issue in Coyote was fixed in Tomcat 4.1.24 I
believe, so you should try upgrading to tomcat 4.1.29 or 5.0.16 and see
what happens.

Subject: Broken pipe exception

Hi I received the following exception!
We are using Tomcat 4.1.18, jre1.3.1_09 and explorer 6.0.2
The exception happens always if I'm adding elements to a table and I'm
refreshing the data from server. The size of this list doesn't matter
because I happens just with short lists:
