I am using the current release and when using JDBC I frequently
get a java.io.IOException: Broken pipe under heavy load conditions.
Is there a limit anywhere on the number of concurrent connections
to a single database or table within a database? Or any other limit
that could stop connections from opening or being forced to close?

There shouldn't be any limit on the number of connections.
What platform are you running the VM on?

Solaris 2.5.1. I am maxing out on something. If I limit the
activity things work fine. Even if I run the same number
of events spread over a longer period of time.
I am using Sun's JDK 1.2 beta3.
I plan to test the same application on linux later today
if possible to see how it does.
I'll listen to any advice.

I don't think you are.
Thinking about it, the only limit you may reach is the memory size of the
JVM, which by default is 16Mb. I don't think that is it as you are getting
IOExceptions, and not something like OutOfMemoryError...

I haven't tried it under 1.2 yet...

It would be interesting to see if you can replicate the problem. If not,
then the only thing I can think is that you are hitting a bug in 1.2
