The only flaw I found is that if you use your own text file you must be very careful when entering the path to the text file and its name.
One misspelled error in the path or file name triggers error into the httpd error log and blows it up to several gigs in a matter of seconds!! This must be corrected. It took me 3-4 hours to figure out this was eating up my whole drive space.
this issue have been fixed in the latest version.
