[syslog-ng] Memory leak in syslog-ng 1.3.7 & FreeBSD?

[George Madden]

I was running syslog-ng 1.2.3 on FreeBSD 3.2 with no problems. I recompiled
1.3.7 and have been running it for the past couple of days. It appears to
have a memory leak.

I've been using top to output the processes to a file and I keep seeing the
mem stats for syslog-ng grow. The system is a fairly busy logger and I did
add the use_dns statement and $HOST parameters. Has anyone else seen this?

Here are the lines from top. I output 2 lines every 5 minutes. This is about
the last 45 minutes or so:
