If it was intensive write, the crash is sooner. This only happens in Win32 (not in Linux) Test script: --------------- <?php $key = 1; $value = 1000; $nbr_of_read_tests = 100000; $shm_id = shmop_open( $key, "c", 0644, strlen($value)); shmop_write ( $shm_id , $value , 0); shmop_close($shm_id); for ($i = 1; $i <= $nbr_of_read_tests; $i++) { $shm_id = shmop_open($key, "a", 0, 0); shm_size = shmop_size($shm_id); $returnedValue = shmop_read ( $shm_id , 0 , $shm_size ); shmop_close($shm_id); } shmop_delete($shm_id); shmop_close($shm_id); ?> Expected result: ---------------- work without any problem. In Linux it works. Actual result: -------------- Crash of Apache ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55070&edit=1
