Public bug reported: In patch [1] 'context' parameter was removed from quota-related remotable method signatures. In patch [2] use of 'context' parameter was removed from quota-related remotable method calls.
Still there are some occurrances where 'context' parameter is passed to quotas.reserve method which is leading to erorr "ValueError: Circular reference detected". 2015-09-08 00:36:34.133 ERROR
