Map and Memory Dumps

40,000 documents going into a Map is causing a memory dump.

20,000 documents gets through the same Map without a memory dump


So we thought, lets batch them and send them through the map.


batch by 1000, still causes memory dump.


Any thoughts?


What kind of a map?


1. A very complex map

2. 5 to 6 SQL queries

3. 3 to 4 groovy scripts

4. flat file to a DB profile


We checked usual suspects


1. To see if there is any groovy code that is accumulating objects. we don't see that

2. we batched the incoming documents and doesn't seem to impact the memory dump


Further challenge


1. This takes 45 minutes to produce the dump

2. So every run is a long process




1. What could be impacting this behavior?

2. what should we look for in the map?
