The Title really says it all. I used to get a crash report when it did that saying it was a Permgen problem, but now it just freezes.
Here is the old error;

Quote from ueva97

Hmm... this is a hard one.
Are you using the new launcher? If so, you should be allocating more RAM to minecraft by doing this:
"Edit Profile" -> JVM Arguments -> change the number (represented by #) in "-Xmx#G" to specify how much RAM you want to allocate to minecraft, for that profile.

If you are using the old launcher, I suggest moving on to the new launcher because it provides better security & backdating options.

Also, 4GB of RAM really isn't much, especially for running that many mods, you should invest in some more to improve performance. Try 6-8GB, that should be enough.

I'll look over the log in detail when I have time and will say if I see anything obviously wrong.

p.s. please don't bump your own thread, no matter how tempting it might be.

Those are all very awesome ideas. Thank you so much. Yeah I am using the old launcher and I never really figured out how to do the RAM allocation thing. But thank you so much.
Haha, sorry about the Thread Bumping. I just havnt been able to play for a long time and I've had this world for a year now and I've gotten so many ideas that i've been getting all Tear-eyed over not being able to play it. But thank you.

Haha, it's pretty much FTB with a few bells and whistles or two.
But yeah, considering my low amount of RAM that may be a good idea... but I like them all x.x.
The one causing the most strain is Gregtech, I believe. I would be happy to get rid of it, but I invested so much into it, haha.
