Just a heads up this has happened more than once. I was in Voidstar the other day when in the middle of the match, my game froze. I went into my task manager to force close it to find SWTOR running at 3.7 million memory http://tinypic.com/r/332sf1v/5. Just to note, I have 8 gigs of RAM. Wth is going on? =/
There was a huge memory leak at Taris that was corrected pretty fast after launch, I dont know why they havent fixed the other planets wich arent as bad as taris was but its noticable after a couple hours on those planets.
