RDi CPU Spike on Mac

In the last couple weeks my RDi will freeze. I check the activity monitor
and it will say the CPU is near 600%. I usually force quit then restart it
again. This happens a couple of times a day.

I use iProjects with a local git repository. Remote reconciler is on to
push all source changes to my home directory on the i. I also use the ssh
connection within RDi to run makefiles for builds.

There are no plugins installed.

Has anyone experienced this or can point me in the right direction of
something to look for that might be causing the issue.

Thanks
