Sorry for the delayed reply, didn't realize my reply was posted.
As for your suggestion, you're a genius! I did what you suggested and as a result it seems like the memory usage was cut to less than 10% what it was. I can still see two instances of the service but they are both using only around 50 mb of memory. Upon inspecting the previous Ext folder I could see almost 300 files, some of them over 15 mb each.
I will keep my eye on the Ext folder and see whether it starts to grow in size again.
Thank you for your help, much appreciated.
