Bug #618

[Robert C Bennett <rb...@ideaweavers.com>]

I am having a problem with Tomcat and JDK 1.3 on linux that seems similar to
bug #618

http://znutar.cortexity.com/BugRatViewer/ShowReport/618

What seems to be happening is that when the connection is reset by the
client (only IE 5 does it in this case), all of tomcat crashes.  I run the
same JDK and tomcat version on another linux box and I do not see this
problem.

Does anyone have any ideas of a workaround or fix that might cure this?  I
am really at a loss as to what might make it work differently on our two
machines.  This happens when the IE user clicks on another link before the
page finished loading. Here is a stack trace:

Costin - its very easy to reproduce with tomcat 3.1..it has this problem a
lot. tomcat 3.2 doesnt seem to.

That seems to me like a JDK problem - probably the 2 linux boxes are using
different libc.so.x.y.z, or something like that.

In any case, a VM shouldn't crash, regardless of the bytecode it runs (
unless JNI is used ). If it crashes - change it, or someday you'll install
a servlet that runs the same bytecode and will crash your server.

bugs and I'll try to reproduce it on 3.3 and 3.2.1 - but its a small
chance to have the same libraries and JDK and conditions. )
