Make sure you're up-to-date - it may be a security hole.
Otherwise: use top(1) and check if at some point you see a httpd process=20
spinning wildly for a long time, while memory grows.
A frequent problem, is that somebody coded an infinite loop, filling a=20
variable and then the process runs outof memory and segfaults.
PHP code like this for example:
$i =3D 11;
$buffer =3D '';
while ( $i !=3D 10 )
{
$buffer .=3D 'hello';
$i++;
}
=2D-=20
