问题
I'm running Matlab R2015b on my mac with OSX 10.11 El Captain. When starting Matlab, changing the directory in file explorer or when saving a file / running an unsaved file. A yellow processing box appears in the bottom left and Matlab consumes more and more resources. When the process is not canceled Matlab uses more than 400% CPU (low memory usage) and does not react for about 10 minutes or even more. Most times there is no feedback what happend - Today I got following error after start up and the "processing" stuff:
Exception in thread "Explorer NavigationContext request queue" java.lang.OutOfMemoryError: GC overhead limit exceeded
