Build: NetBeans IDE 8.1 (Build 201510222201) VM: Java HotSpot(TM) 64-Bit Server VM, 25.73-b02, Java(TM) SE Runtime Environment, 1.8.0_73-b02 OS: Mac OS X 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.
