Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

I have more that 1730 php files.
I don't know which one is generating the php cores.
Compiling with --enable-debug may help ?
 [2006-04-11 23:29 UTC] sniper@php.net 
As soon as we get a script that causes this the sooner we can actually do something about it. Otherwise: Keep the status as feedback and let the report rot if you can not come up with a reproducing script.
 [2006-04-12 06:41 UTC] thetaphi@php.net 
If it not always reproducible it could be a stack size problem. When using PHP in the SunONE webservers it is recommended to raise the stacksize in magnus.conf. See bug #27231 and documentation for help about that. For me a value of 256000 as minimum helped (the default is 128k).

No feedback was provided for this bug for over a week, so it is
being suspended automatically. If you are able to provide the
information that was originally requested, please do so and change
the status of the bug back to "Open".
 [2006-04-20 15:00 UTC] bruno dot fernandes at idw dot pt 
a stacksize of 512kb solved the problem.

Thanks everyone.
