Have you ever run into the following error message in PHP?

Fatal error: out of dynamic memory in yy_create_buffer()

I ran into this not long ago and had a hard time understanding the problem, though the fix is simple.  This is a bug in PHP versions prior to 5.2 on BSD based systems.

Short of upgrading PHP to a newer version, open the php.ini file and toggle the output_buffering variable from “Off” to 4096. This variable can be found in the “Language Options” section of the file. This will have the side effect of slowing down the PHP interpreter, but it should also eliminate the bug by forcing the interpreter to flush its buffer to the web socket regularly while executing the file requested.
