I've tried a simple registry script that uses flock() (on WinXP), as well as one that just prints out the environment variables, using apache-2.0.40 and a recent cvs mod_perl-2 build. Using ApacheBench as ab -n ddd http://localhost/perl/script_name (where 'ddd' is the number of requests to do), on my system, when ddd exceeds about 1500 with perl-5.6.1, the tests hang, but things are OK in this realm with perl-5.8. So this problem may not have so much to do with flock(), but perhaps more to do with threading under perl-5.6.1 on Win32. If you're interested in comparing for your particular script, there's a perl-5.8/Apache/mod_perl binary, perl-5.8-win32-bin.tar.gz, at ftp://theoryx5.uwinnipeg.ca/pub/other/ - installation instructions are in the associated .readme file. -- best regards, randy kobes
