Caution: you are entering unchartered waters. first of all: you must use 5.8.0 with threaded mpms perl 5.8.0 internals are thread-safe, so does mod_perl 2.0-dev. By saying that perl is thread-safe, I mean that operations like push, =, /, map, chimp, etc. are thread-safe. Operations that involve system calls, may or may not be thread-safe. This varies from OS to OS, and even varies for various versions of the same OS. e.g. localtime() is not thread-safe on platforms where asctime(3) is not thread-safe. other problematic ones are readdir(), srand(), ... there is another important issue. what some people are referring to as: thread-locality. Certain functions executed in a single thread affect the whole process e.g. if you chdir() in one thread, all other thread now see the cwd of that thread that chdir'ed. Other problematic functions are umask(), chroot(), %ENV... Getting back to the Justin's question, it's quite possible that thread-safety problems kick in. It could be that flock is not thread-safe. But I think the real problem is with chdir(), because Apache::Registry chdir()s to the dir of the script. Stop using Apache::Registry and start using ModPerl::Registry, which doesn't chdir(). Of course you cannot do any operations with relative path anymore. Arthur Bergman is working on some solutions for chdir(), but nothing was released so far. So you will have to wait or help Arthur to finish his work. So first try using ModPerl:Registry, which I expect will resolve the issue. If that doesn't help, please supply a *short* script that reproduces the problem. Which of course may not exhibit the same behavior on a different platform, but at least we can do some sanity check. __________________________________________________________________ Stas Bekman JAm_pH ------> Just Another mod_perl Hacker http://stason.org/ mod_perl Guide ---> http://perl.apache.org mailto:[EMAIL PROTECTED] http://use.perl.org http://apacheweek.com http://modperlbook.org http://apache.org http://ticketmaster.com
