Hi all.
I have been having the same exact issue in regular playback with different sorts of video files. I'm using a 64-bit version of Arch Linux (2.6.35-ARCH #1 SMP PREEMPT) and VLC 1.1.4.1 (The Luggage). After every ten days or so, give or take a bit, VLC seems very prone of going bonkers with its resource consumption. I usually give up and reboot at that point, but as it happened an hour ago, I decided to check it out, and after two consecutive and extremely painful freezes with the same exact video file, tried it with another video file, which worked fine. I tried again with yet another one, which worked fine as well. Although the memory consumption was still up to 1.3 GB, which is quite a lot.
And yes, when I went back and tried with the original file I was trying to play, I got the Frozen VLC Syndrome once again.
Now, I understand the difference between the circumstances these weird things seem to occur - I don't have streaming media running 24/7 either on or via the silly darn program. In my case, it's just a question of using VLC quite a lot over a relatively long time. Nevertheless, it would seem rather apparent that the issues we're facing might be more or less related to each other.
In my case, the Frozen VLC Syndrome seems to hit quite suddenly, without any slower increase of resources over a longer period of time. It just slams me in the face with a sledgehammer. Killing the process, even when it's done properly - with wolves howling at the background, when the Moon is full - doesn't cure the disease. Now, what I wonder is that why other video files are playing back nicely, but not the one that didn't understand my supreme power. I tried to play the file with xine-ui - without any problems.
