Version 1.6 compile errors

I just upgraded from Arduino 1 to 1.6. When compiling, I got numerous errors. After numerous attempts to compile, the number of errors has diminished to the following:

Global variables use 420 bytes (20%) of dynamic memory, leaving 1,628 bytes for local variables. Maximum is 2,048 bytes.

760088463 [main] avr-g++ 144084 proc_subproc: couldn't get proc lock. what 6, val 17488360

I am a newbie and I have been unable to locate an on-line solution for this. I would appreciate any help I can get.

Thanks

Operating system?

Do you have Cygwin installed?

Downgrade to 1.5.8 is my suggestion. Or even 1.0.6 unless you are using a Due.
