Are there any plans to do anything about known bugs? I have several that
I regard as fairly important to get fixed:

In connection with this, the following message may also be important:

And then there's the long standing memory leak:

... which we currently work around by restarting the DHCP servers at
regular intervals.

These bugs involve servers in a failover pair, and around 100k leases
with the lease time set to one day. The failover pair runs on FreeBSD
7.0-STABLE. The reconnect bug has also been reproduced on Linux. As
far as I know other people have seen the memory leak problem on Linux
(also running in a failover pair).
