- Official Statement from Red Hat (05/29/2007)
-
The memory_limit configuration option is used to constrain the amount of memory which a script can consume during execution. If this setting is disabled (or set unreasonably high), it is expected behaviour that scripts will be able to consume large amounts of memory during script execution.
The memory_limit setting is enabled by default in all versions of PHP distributed in Red Hat Enterprise Linux and Application Stack.
