All,
                I�m running a continuous capture of data. I�m trying to 
use a ring buffer of 25000 files with an 8mb file size. The problem is 
that the ring buffer starts overwriting after 10000 files. I�ve tried it 
with dumpcap and tshark. The command is using the �b files:25000 �b 
filesize:8192. Is there a limitation to the size of the ring buffer for 
dumpcap and/or tshark?
Turns out that if you specify the number of files as 0 then 
dumpcap/*shark will create an unlimited number of files.  I don't know 
if that's acceptable or if you really need it to roll over at 25,000, 
but it's an option.
