IDEA extremely slow!

Environment:
Ruby On Rails

The IDE seems to be extremely slow, and it’s causing other applications to respond extremely slowly as well. I’ve restarted my machine a couple of times thinking the problem might be the computer itself, but I’ve noticed that other applications respond normally until I start IDEA. When I run a unit test (on a single method), the CPU load stays higher than seems normal 15 – 30%, spins for almost 3 minutes, then returns this error:

(I'm using a Ruby script called remote_test_server to run the test)

Invalid argument

Could not obtain drb reference to remote test runner on port 61690.

Is it running?



In the remote_test_server tab I get the error:

failed to allocate memory

Any thoughts, please help!

Thanks.
