sonewconn error/log entries

[esquire1968 0]

Hello!

In my log I see a lot of entries like that:

sonewconn: pcb 0xfffff80068af7570: Listen queue overflow: 193 already in queue awaiting acceptance (819 occurrences)

The command netstat -Lan shows many open connections:

Proto Listen Local Address
tcp4 0/0/128 10.0.99.1.443
tcp4 193/0/128 *.18443
tcp4 46/0/128 *.18081
tcp4 0/0/128 127.0.0.1.953
...

After a restart of DNSBL all connections are closed.

tcp4 193/0/0 *.1844

pfBlockerNG-devel ... latest version.

What‘s wrong? What can I do?

Many thanks,
Thomas
