#37140 [Opn->WFx]: PHP / Apache can crash when accessing large files

ID: 37140 Updated by: danbrown@php.net Reported By: david at acz dot org -Status: Open +Status: Wont fix Bug Type: Documentation problem Operating System: SuSE Linux 9.3 PHP Version: Irrelevant New Comment: This is an Apache memory limitation, not a crash caused by PHP. As such, reference to the limitations (and potential workarounds) would be the scope of the Apache documentation, not the PHP manual. Previous Comments: ------------------------------------------------------------------------ [2006-04-19 22:56:59] david at acz dot org 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 this bug report at http://bugs.php.net/?id=37140&edit=1
