I don't have any limits set....
ulimit -a shows the following
core file size (blocks) 1000000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max locked memory (kbytes) unlimited
max memory size (kbytes) unlimited
open files 1024
pipe size (512 bytes) 8
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 4095
virtual memory (kbytes) unlimited
And if I launch the test
$ php -d max_execution_time=900 -q -e ./test.php
OK!
PHP Fatal error: Maximum execution time of 30 seconds exceeded in
