[syslog-ng] Do stats cause memory leak

We are running git head download post 3.9.1 and the memory footprint seems to continually grow. Looking at the statistics for queued messages I found none, but discovered that we have nearly 22,000 statistic sets for a total of 68195 tracked statistics. % /usr/local/sbin/syslog-ng-ctl stats | wc -l 68195 It it possible that all of these statistics take up a non-trivial amount of RAM? USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 1489 79.2 61.5 12134140 10139760 ? Ssl Apr24 41581:22 /usr/local/sbin/syslog-ng That is a 12GB footprint after 1 month of uptime. Evan.
