malloc() failure - single function document

Hello, all. I've got a problem, and this is the best place I know of to find the solution. I have three PHP programs I'm trying to run. One functions just fine (located in the home directory, this is a simple mileage tracker for a couple of my automobiles). One is a feedback form (SMTP), and the other is a test file only has : <?php phpInfo(); ?> Here's the results : mileage.php - works perfectly phpinfo.php - results in : httpd in malloc(): error: allocation failed [Thu Jun 24 10:18:29 2004] [notice] child pid 19655 exit signal Abort (6) feedback.php - results in : [Thu Jun 24 10:19:23 2004] [notice] child pid 19652 exit signal Bus error (10) Those log messages are not what I call good. On the phpinfo.php script, the memory usage on the server goes through the roof before the messages get printed to the log file. I'm using FreeBSD5.2-RELEASE, and PHP 4.3.6 running under Apache 2.0.49. I've compiled both apache and mod_php from ports (similar to "rpm -i"), and also directly from the source code, to no avail. Does anyone have any ideas as to what is actually occuring? Joe
