ID: 27231 User updated by: herman at frontier dot nl Reported By: herman at frontier dot nl -Status: Feedback +Status: Open Bug Type: Reproducible crash Operating System: SunOS 5.8 PHP Version: 4.3.4 New Comment: Sorry, forgot to mention: no, using the CLI (at least scripts #1 and #2) they run OK. Previous Comments: ------------------------------------------------------------------------ [2004-02-12 20:52:26] iliaa@php.net Does it crash with PHP-CLI? ------------------------------------------------------------------------ [2004-02-12 14:59:48] herman at frontier dot nl Description: ------------ When trying an PHP application (which uses generated code, some rather quite large files) on Sun server running Solaris 8, the SunONE webserver 6.1 and PHP 4.3.4 using nsapi, one of the scripts crashed the server. After some experimenting, it seems the size of the script file triggered the crash: a PHP script > 128KB will bring down the server, a script < 128KB will not. To complicate matters a bit, if a small script includes a large script, the server will also crash, but if a small script will include two "half size" scripts, it will not. The server seems to run other PHP scripts well, and is also used to run applets through its nsapi interface without problems. PHP has been compiled as per instructions on the PHP website, with mysql disabled, and ldap and oci8 enabled. Reproduce code: --------------- The test scripts consist of: <?php echo "hello"; exit; $a = "123456789012345678901234567890123456789012345678901234567890"; // previous line copied till the script is large enough ?> The scripts can be found at: http://www.ozuzo.net/phpbug/test1.php.txt => WORKS http://www.ozuzo.net/phpbug/test2.php.txt => CRASH Include examples: http://www.ozuzo.net/phpbug/test3.php.txt => WORKS http://www.ozuzo.net/phpbug/test3a.php.txt http://www.ozuzo.net/phpbug/test3b.php.txt http://www.ozuzo.net/phpbug/test4.php.txt => CRASH http://www.ozuzo.net/phpbug/test4a.php.txt Expected result: ---------------- The word "hello". Actual result: -------------- The server crashes with the following message (no entry in the PHP log): failure (25268): CORE3107: Child process closed admin channel fine (25268): CORE3061: signal_handler_thread: received signal 18 fine (25268): CORE3049: Primordial process detected child 25296 died: status 11 fine (25268): CORE3050: Is our child, will spawn replacement fine (25268): CORE3062: Unlinking of /tmp/<servername>/.cgistub_25296 returned -1 fine (25268): CORE3047: Server spawned worker process 25305 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=27231&edit=1
