The rule of thumb is 4 GB per 12 detection servers, and there are other factors at play so give it a bit more than you would think necessary.

Component : Web Prevent
Edit SymantecDLPDetectionServerController.conf Located at:
C:\Program Files\Symantec\DataLossPrevention\EnforceServer\Services "Windows"
and adjust wrapper.java.maxmemory to the appropriate value for the environment.
In this case, we increased to 16GB
Restart the SymantecDLPDetectionServerControllerService
Make sure the machine has enough physical memory on the box to make the correction.
