I am getting the following exceptions. If I use any built-in filters, it works fine. I searched around and one of the suggestions was to increase the lease timeout. Since it works fine for built-in filters, I am assuming that this is not the case. Is it that there is something wrong with my filter implementation? Regards, Raghava.
