You may indeed have hit upon the multithreading limitations of mod_perl-1.x on Win32: http://perl.apache.org/docs/1.0/os/win32/multithread.html If possible, you could try upgrading to mod_perl-2: http://perl.apache.org/docs/2.0/os/win32/install.html to see if that helps (mod_perl-1.99_xx is the development version of mod_perl-2 - the mod_perl ppm package at http://theoryx5.uwinnipeg.ca/ppms/ is currently at 2,0,0-RC4,0, which is the latest mod_perl-2 release candidate). Note that mod_perl-2, as well as requiring Apache-2, requires perl-5.8.x (an ActivePerl 8xx build) on Win32. -- best regards, randy kobes
