--- Comment #11 from Arne Claus <arne.claus@trivago.com> ---
We haven't tested it yet on FreeBSD 10.1, but there were some updates on the
memcached ticket by other users having the same problem.
One thing that might be interesting:

"When it stuck - in kernel log 
kernel: sonewconn: pcb 0xfffff80328c68930: Listen queue overflow: 1 already in
queue awaiting acceptance (14114 occurrences)
and this line disappears from netstat -Lan
tcp4  0/0/1024       192.168.0.32.11211"
