Operating system: Linux 2.6.24-gentoo-r8
PHP version:      5.2.10
PHP Bug Type:     Unknown/Other Function
Bug description:  script crashing when running simultaneously

Description:
------------
When running 2 batch scripts simultaneously, getting weird errors like:
Fatal error: Call to undefined function substr() in xxx.php on line 125

The problem is obviously not related to the source code as it happens with
built-in functions.

It also happens with custom class functions sometimes.

The problem doesn't seem to exist when a single php process is running.

Unfortunately the problem is not reproductible intentionnally.  The exact
same code and conditions will sometimes work and other times fail.
