Cancelled SSL connections cause Tomcat to stumble
Summary: Cancelled SSL connections cause Tomcat to stumble
Product: Tomcat 4
Version: 4.1.18
Platform: All
OS/Version: Other
Status: NEW
Severity: Critical
Priority: Other
Component: Connector:Coyote HTTP/1.1
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: ceki@apache.org
To reproduce the bug:
1) Configure an SSL connector:
In server.xml, uncomment the SSL connector element and set its
minProcessors and maxProcessors attributes to small values, say 2.
2) Create any trivial web-application. This web-app should contain a
large file, for example a zipped archive file.
3) Using IE or Netscape, attempt to download the zipped file with
SSL. When prompted to open or save the file, cancel the request. This
will cause the following exception:

If you repeat step 3 several times, all connectors will become
disfunctional and Tomcat will eventually stop responding to HTTPS
requests.
The following bug can be reproduced on XP or Linux with JDK 1.4.1 and
Tomcat 4.1.18.
In addition, if your web-app uses log4j and struts 1.1x, and if you
place commons-logging and log4j.jar in WEB-INF/lib, then you will get
the following error in catalina.out (on top of the previous
java.net.SocketException):

This makes the bug quite hard to identify, because the user who was
using log4j and commons-logging in lead to believe that the bug was in
"logging" where as the bug is in the connector *and* in the deployment
of commons-logging jar files:
TOMCAT_HOME/server/lib/commons-logging.ar
TOMCAT_HOME/commons/lib/commons-logging-api.jar
WEB-INF/lib/commons-logging.jar
WEB-INF/lib/log4j.jar.
