#37140 [NEW]: PHP / Apache can crash when accessing large files

From: david at acz dot org Operating system: SuSE Linux 9.3 PHP version: Irrelevant PHP Bug Type: Documentation problem Bug description: PHP / Apache can crash when accessing large files Description: ------------ The manual mentions how to build PHP with large file support, but it should also warn that PHP / Apache can crash when accessing large files. Reproduce code: --------------- $fp = fopen("/tmp/large.dat", "w"); fseek($fp, 2147483646); fwrite($fp, "xx"); Note that there is not actually a filesize rlimit set: $x = posix_getrlimit(); echo $x["soft filesize"] . " " . $x["hard filesize"]; Returns: unlimited unlimited Expected result: ---------------- PHP should write one byte to the file (the second byte puts it over 2GB). Actual result: -------------- [Wed Apr 19 17:44:13 2006] [notice] child pid 26994 exit signal File size limit exceeded (25) -- Edit bug report at http://bugs.php.net/?id=37140&edit=1 -- Try a CVS snapshot (PHP 4.4): http://bugs.php.net/fix.php?id=37140&r=trysnapshot44 Try a CVS snapshot (PHP 5.1): http://bugs.php.net/fix.php?id=37140&r=trysnapshot51 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=37140&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=37140&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=37140&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=37140&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=37140&r=needscript Try newer version: http://bugs.php.net/fix.php?id=37140&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=37140&r=support Expected behavior: http://bugs.php.net/fix.php?id=37140&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=37140&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=37140&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=37140&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=37140&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=37140&r=dst IIS Stability: http://bugs.php.net/fix.php?id=37140&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=37140&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=37140&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=37140&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=37140&r=mysqlcfg
