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");
fs

($fp, 2147483646);
fwrite($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)
