Riflettotv is a nice webtv that transmit films on demand for free in Italy. The site is made with streamcast player and flash. I use it occasionally on other machines/browsers and never had a problem but on Os X and Safari i can't finish a movie becouse i ran out of memory. Usually after 1 hour and a half the safari process use 1.6Gbyte of memory, the system slow down and some time after that the download of stop. At first I thought it was flash fault but I tried watching a movie with firefox 2.0.11 and the memory usage of the system was constant for the wole movie.
To reproduce the bug just visit the link and pause the film. Flash will continue the download on the background.
This is a duplicate of bug 13705 (High RAM usage while playing Flash videos) which was fixed in r28006.
