Hoping that the memory issues in 8 would've been fixed, i upgrade to 9 and it's much worse. This, however, doesn't seem to be a problem for others running IDEA 9 on windows. I am running IDEA on a MAC with apple's jdk 1.6_07, 64 bit server. It drinks memory and i have to restart IDEA several times a day. Before switching back to 8, i am wondering if anyone else has this issue and/or a magic jvm flag that helps fix or prolong the time between restarts. For an IDE that costs so much, this is a really bad situation to be in.
