Currently I can't use my eclipse project. I'm using ArchLinux:

Eclipse Juno 4.2 (extra/eclipse 4.2.2-1)

The problem here is when I try to change anything in my project and eclipse goes to rebuild it. A process systemd-coredum eats all memory:

COMMAND                   %MEM    RSS     %CPU

pulseaudio                0.3     10.65   2.0

I have ulimit -c unlimited in .bashrc file and a symlink in the coredump conf

$ ln -s /dev/null /etc/sysctl.d/coredump.conf
$ systemctl restart systemd-sysctl

But I can't solve this issue.

To stop the coredump you can disable it by limiting it's resources to 0:

$ ulimit -c 0

Check out this thread on the ArchLinux forums, looks to be an active problem as of 7/2013, https://bbs.archlinux.org/viewtopic.php?id=154511. The thread had a couple of posts that mentioned the ln -s /dev/null ... method as no longer working.

This wiki article titled: systemd in the ArchLinux wiki had additional details.
