To diagnose this, your friends are
- samba logging turned up high and tail -f
- strace or truss running on the fd that correponds to the port
- wireshark capturing the data on the net at the time. and
- a stack trace at the time of the problem (more about this later).

Your eyeballs are really good for this: you'll see in the first three cases
 - a request go by, followed by a long long wait, followed by a reply
or
 - millions of request, back to back.

The former is likely, and the problem will be in the handling of the
request.
If you can catch it in the problem state, capture a  stack traceback
with gdb.
Between the time data ("horizontal") and the stack trace (vertical)
you'll end up with a candidate to investigate

The latter (gadzillions of requests)  is less likely, but the same data
is used to diagnose it. Look for the same request being retried repeatedly.
