Based on your memory usage I am thinking you are pulling back a decent amount of data. Your checkpoint value is quite high suggesting your data set is very large and this is not a new forwarder, so this likely worked before. I am guessing the data set has gone up recently or there was an issue that caused you to be able to pull for a period of time, which caused this to come to a head. Try upgrading to 2.4. The below bug, which was fixed may be what is... well... bugging you. 🙂
