Re: [tycho-user] 0.23.0: Problem creating zip 
Can you give Maven more memory, eg., with

MAVEN_OPTS=-Xms512m -Xmx1024m -XX:PermSize=128m -XX:MaxPermSize=256m

Are you using JDK 8?

Are you on linux? If so, maybe it's a problem w/ your OS config:

http://stackoverflow.com/questions/9011772/too-many-open-files-error-but-lsof-shows-a-legal-number-of-open-files?rq=1

Or maybe it's a flaw in Tycho 0.23, leaking file descriptors?

Hello,

I’m trying to pass from tycho 0.22.0 to 0.23.0. The build fails with
0.23.0 on the archive-product goal from
org.eclipse.tycho:tycho-p2-director-plugin:0.23.0:archive-products with
error Too many open files.

It works when using 0.22.0 tycho version.

The files to be zipped are an Arm toolchain hosted on a fragment. The
toolchain contains many files with many directories.

Error code are :
