I plan to get to this this week - I'm also hoping to look into rolling the Solaris threading fixes into the 2.1.2-tobe CVS branch. Anthony

Well I've tested your script with an old backup of Zope 2.3.2 on an Win NT SP 5 machiene. There are no problems. The script runs in one window and in the other I can surf the management screen. My Solaris can't do that.

On Solaris and on NT I could see your second problem. When I press cancel o n the Browser the process/thread doesn't stop. Thats really a problem. I started your script twice and the machiene (NT) is nearly not usable anymor e. But thats better than Solaris - there I can't start the process twice!

For me I've prooven that there is something VERY WEIRD with the Solaris Zope. OK it might not be Zope but Python. As for me I need an answer / solu tion desperately! Any ideas anybody? My primary guess is, that Solaris doesn't relese the threads after using them. I've tried a threaded Python script on my Solaris machiene and that had no problems. But I must confess I have no clu e on how Zope Threading works. Therefore my test doesn't proove anything really.

By the way...it also shows how fast Zope really is because if I run "singlethreaded" and Zope can still serve a few thousand requests a day tha ts really not bad.
