Listen Queue Overflow & High memory usage

[axsdenied]

I first noticed double the memory usage of the router than usual.  With my configuration it usually uses anywhere from 2-4GB.  It's currently using over 8GB of RAM.

I ran a netstat -Lan and got the following (*filtered):
Proto Listen Local address
tcp4  193/0/128   *.53

This pointed me to DNS; running unbound, I attempted to restart the service but I saw no change in the listening queue or memory usage.

I continue to get the following notices at consol:

sonewconn: pcb 0xfffff8010279d1f0 (0.0.0.0:53 (proto 6)): Listen queue overflow: 193 already in queue awaiting acceptance (3 occurrences)

Anyone else get this or know what to do here?
