Could you get a tcpdump -v of that problem occuring?  I find what your
logs are showing hard to believe, there must be something really strange
occuring.  Can you also show the output of netstat for the ports in
question to show what state the sockets on either end are in during that
time period?

Also, does netstat -s show any counters increasing that talk about listen
queue overflows or any packets being dropped?
