Esper 6.1.0 out of memory
- Iam using Esper to get the count of vehicles from a traffic stream for 1 min running window,
- It is working fine, iam able to get the count based on the grouping of sensor, vehicle type and direction.
- It runs for a day but at the end of the day it gives out of memory, can you please help us resolving this. 4.I have used @Hint to reclaim, please suggest if the EPL has to be changed
