Mac Running out of memory

[luca]

Hi,

I play on a Private Pack server with some friends and I have a problem.
I run the pack out of a multi-mc instance and when i join within 10 minutes I crash. I get the "out of memory" error I've allocated Multimc 1/2 of my computers ram (2GB) and i still get the crashes any help?

thanks,
Luca

Try adding -XX:MaxPermSize=128M under advanced options>additional java parameters under the options tab. If that doesn't work post a crashlog to pastebin.

is this on multimc?

You can do this in both the ftb launcher and multimc, for the ftb launcher use the instructions I posted above, for multimc it's under the java tab in the settings dialogue.

There's a memory leak somewhere.

No, I think this is the issue with macs where they don't allocate enough perm space.

Not on a mac but I've done that and there's still a memory leak. In fact it did nothing noticeable at all.

There's definitely a memory leak(or multiple), but the issue here has to do with PermGen space allocation. I'm honestly under the assumption that it's an issue in the code for a mod(or mods), but it's mainly occurring on Macs either way.

Everyone could crash due to memory thanks to the memory leak being there, but people that allocate a lot of RAM to the game in general aren't likely to notice. This issue, on the other hand, is not remedied by allocating more RAM through the normal means because it's handled separately.

Edit: Usually users would never notice, or have any reason to know about PermGen. It holds class data etc. Classes(and a few other little things) are loaded into the PermGen space rather than the heap.
