out of memory building c extensions

Peter,

This is most likely your machine. http://www.petefreitag.com/item/746.cfm

Are you sure you've terminated all your applications? No memory hogs?

ps aux | sort -nk6 | tail

Furthermore, the ant output suggests that your machine is running out of resources while ant is executing compile-jruby target. It has nothing to do with C extension.

I just ran it again. Usual hogs closed (rubymine and chrome), leaving over 2gb free. (I've got istat menus, which is great for this too).

At no point while this was running was there less than 1.8gb of free memory.

ps aux | sort -nk6 | tail

Peter,

You have two rails console processes running. You should terminate them and try again.

I got this on a JDK8 build too. I think there might be a bug in javac.

We ran inso this issue more frequently and bumped up the max memory for the compile phase.
