java - Multiple tests on the same IEdriver instance - memory issues

Question

I'm running lots of selenium tests on my node which is windows machine. In order to speed up test execution by avoiding starting/closing IEDriver instance after every test I decided to reuse the same driver instance for every test. Everything works fine with firefox and chrome, but IE11 is having serious issues. After about 30 minutes IE freezes without any exception and execution stops, it completely loses connection with my node. I can see that IE11 process (iexplore.exe) uses massive memory resources (1.5 GB or more) and I need to kill it using task manager to shut it down.

Did anyone face this kind of issues and how to avoid it (except to create new driver instance for every test), is it even possible to run many test on the same IEdriver instance?

I'm using IEDriver 3.0.0, Internet Explorer 11. Same thing on windows server 2012 and windows 8.1 machines.
