Problem with mod_jk 1.2.8 (and 1.2.10) and Tomcat 4.0.4

[Laurent LE PRIEUR <la...@ac-nancy-metz.fr>]

Hello,

I have a problem of ping pong between the connector mod_jk and tomcat 4.0.4 which entraine a significant load network.

Sequence 1234 APACHE MOD_JK to TOMCAT
Response AB (TOMCAT to APACHE MOD_JK)

http://jakarta.apache.org/tomcat/connectors-doc-archive/jk2/common/AJPv13.html


I manage to reproduce the problem in the following way:  I have an application which allows me to send a file (I a file of 5 Mo takes for example) and I the transfer stops while close my navigator.... at this time there sequence AB/1234 never stops (infinite).  Useless to say to you that if 20 or 30 users make celà, one arrives at a load very significant network.


tcpdump on localhost showed me that there is continues traffic between
both the httpd/mod_jk and the tomcat server (ajpv13).  The traffic is
always the same.  A request from the container (AB -> in ajpv13
this means "Get Body Chunk") and a reply from the server (1234|00|00 ->
this is an 'empty packet' telling there is nothing more to be sent).

I found only one mail in this direction in mailing list archive.  And no response to this problem.  Can you help me?

This sounds similar to a problem that is fixed in 3.3.2,
4.1.31 and 5.x.

Did you tried your app with Tomcat5 or Tomcat5.5?
Perhaps the problem is not with the native side of mod_jk.

You can post your application if unable to install the Tomcat5.
