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 avoid embedding huge scripts into the report. ------------------------------------------------------------------------ [2004-02-16 03:42:54] yury at gorodok dot net Description: ------------ shmop doesn't work properly. I start sh.php, which creates shmop segment and write a strring there. After that I start hh.php, which should read string and write it in my browser. The hs.php deletes segment. On FreeBSD with PHP 4.3.4(apache module and command line) this works just fine. But on Win2000SP2 with PHP5.0.0b4(commandline and cgi) I can access shared memory segment only while the first script is running (I' ve adde sleep(30) in it for test reasons). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27271&edit=1
