Packet Correlation Classification daemon uses blobs and the db variable pccd.maxblobsize configurable range is from 512 to 32720 with a default value of 4090. On some system not requiring large blob, a minimum of 32 MB is more appropriate.
Memory usage increased.
Not able to lower the range below 512.
