Hi Charini, How large are these events ? It's unlikely that Max attribute aggregator has caused this since it only keeps the values. The most probable reason is memory is not enough to hold the 3min window. We should be able to confirm this by analyzing the generated hepdump.
As Abimaran has mentioned you should be able to overcome this issue by increasing the Xms and Xmx values. I assume you have used the default values for Xms and Xmx.
