Yes there were a couple of memory leaks identified where many connections were opened and closed over an extended period of time - these should now be addressed in the latest release.
Thanks. We try to migrate to last stable version of AS in the future.
I would like to point that per day we have maximum 2-3 jmx-connections. So for two months there were maximum 120-180 connections using jmx/cli interface. Seems not so many...
