There is an bug in version 2011011701 where the function turnitintool_tempfile() gets stuck in a loop when attempting to create a temporary file on linux. The function is only used with Moodle 2.0 files so only effects Moodle 2.0 installations and only causes an issue where the temp_dir set by PHP has no directory seperator on the end of the string. This mainly occurs in linux as the temp directory is /tmp by default.

This has been raised by 2 users through the helpdesk and on the Moodle.org forum.
