Update:

jdk 1.3.1 does also not work with sablotron. It's 1.2, which has no
problems...
see http://bugs.php.net/bug.php?id=13344
for more about that

We don't use sablotron here too.

The script is about 20 lines long and only interfaces to a SDK
implemented in Java. The Java part does some complicated image
texturizing tasks. The php part only calls the apropriate methods.

We use apache 2 here and now I had the idea to simply change the max
request per child value. Now the questions are:
Would it make a difference to use apache 1.x ?
As I know now the change of the java module is a little tricky, but
does someone know what causes the error.
As I use this box only for exactly this one task I am flexible with the
environment.
And if you say that the problem can be minimized by change the child
lifetime I am very flexible with that.
As a restart of apache solves the problem this may be an issue.

What is Sablotron? I´m not using it... I'm running PHP on Win2K + IIS,
ISAPI version.

Hi 

Do you use Sablotron? Does it work without it?

I know from my experience under Linux, that ext/java with jdk1.4 and
Sablotron doesn't work. But jdk 1.3 does fine.

Also, I noticed that before reporting the message 'Unable to Create
Java Virtual Machine', I get an error saying something like 'PHP found
a violation access at <ADDRESS>'. After that I only get errors. I don't
know if before every virtual machine error there is an error like this.

False alarm! I just got 'Unable to create Java Virtual Machine'
executing the first example that is in the docs... 
afterwards I got periods of errors and periods of success!

Definitively there's something wrong. Ideas?
