Only one definitely lost record was present, which should be fixed by
the patch below. Some of the remaining leaks seem to be part of buffered
messages not yet sent to destinations, but they were still reachable.

Some reload tests would be appreciated (e.g. run syslog-ng and reload it
a couple of times with your configuration and load), that might reveal
some real leaks.
