------- Comment #4 from ulf.lamping@xxxxxx  2007-10-10 16:05 GMT -------
So we have: input -> buffer -> output

If the input rate (incoming packets) is higher than the output rate (display of
packets in Wireshark), a ringbuffer with limited size *must* exceed it's limit
sooner or later. This is a principle problem and we can't do anything against
this. BTW: Simply dropping some packets on the incoming side or in the buffer
is not an option here IMHO.

Your real problem here is a peak load (20MB file + overhead), that obviously
doesn't fit into the amount of ringbuffer (3MB) available. This causes the
buffer to overflow and therefore the error message (ok, the error text itself
could be improved).

Try to increase the number and the size of the ringbuffer files (e.g. 10 files
with 10MB seems more reasonable in your case).

I'm marking this on as invalid, as we cannot avoid a buffer overflow in this
scenario ...
