Hey there. I'm running into "OOM: Java heap space" exceptions trying to aggregate twitter messages before pushing them to s3. (Xmx/Xms = 1.5g; there's definitely sufficient free memory available when the exceptions happen) I've also tried to use camel-leveldb as the AggregationRepository but without luck. Smaller batch sizes (i.e. 100) work just fine... 5000 aggregated messages should also take up just 60mb-ish (assuming an average of 3000chars per message).
The relevant code can be found here: https://gist.github.com/th0br0/a1484ea1ad18b8b20c25 Could somebody point me to what I'm doing wrong? Thanks a lot!
