Yup, I mistakenly pasted an older version of the code, As per your example in the original bug I moved it into a threadlocal member of the class and sharing it in the lambda and there is def a considerable drop in memory usage, I am just using the HTTPClient at the moment will check out the example thanks again for the quick response!

Anyone else who might come looking for the timer issue revs with the timer in lamba code here https://gist.github.com/abhiguru/68041ef47969bb63b7a375aee99d1c93/revisions

Actually, there was another thread leading to the requestData which is why runInBaseThread was required.
