User Comments:
GUEST: The running netbeans process wasn't accessed for 4 days. Now I wanted to contiune to programm but netbeans stopped responding.

derikd: If I let NetBeans sit idle overnight,  then when I come in the morning it will be consuming 100% of all CPU resoureces.   

Someitmes, as was the case here, NetBeans is non-responsive to the OS and I am required to use Force Quit to recover control of the CPU resources.  Othertimes I can just close it and reopen.

Running OSX 10.11.6.   On a MacPro mid 2012 edition (16GB RAM and Quad Core Xeon).  

This wasn't a problem until the last few months.
