Bug: mute does not always work

[Psilo]

I have a config with "mute 10" on my server, but for some message types, the number of consecutive messages can exceed 10 in my log file.

First message type (I have masked the user name and IP address):

Fri Dec 3 18:35:28 2010 username/90.XX.XX.XX:62750 Need IPv6 code in mroute_extract_addr_from_packet

Second message type (I have masked the IP address):

Thu Dec 2 21:58:43 2010 188.XX.XX.XX:1223 WARNING: Bad encapsulated packet length from peer (56620), which must be > 0 and <= 1560 -- please ensure that --tun-mtu or --link-mtu is equal on both peers -- this condition could also indicate a possible active attack on the TCP link -- [Attemping restart...]

I don't care about the cause of these error messages, but for these two types of messages, I can get dozens of them, the "mute 10" does not apply.

Edit: I am using OpenVPN 2.1.4 on Linux Debian 5 x86
