[Ethereal-users] Ethereal devours CPU Power

["Felczak Andrzej" <Andrzej.Felczak@xxxxxxxxxxxxxxxxxx>]

When I use Etheral with the ring buffer (10 files, 50000 kb per file) it
works the first time without problems. 

I have a 2 GHZ PC with Windows 2000, Ethereal 0.9.7 and I am saving the
data to the local harddisk. There is almost no traffic on the network. I
have disabled the name resolution of ethereal.

In the beginning ethereal uses almost no CPU power (0%).  Then, after a
couple of hours, ethereal starts to consume more and more of the CPU
power, 5%, 10% or even sometimes up to 100 %.

This first happened by a customer of us (using ethereal 0.9.5) and then
I started to investigate the problem and could reproduce it without
difficulty. If you stop ethereal and then start it again it consumer a
lot of CPU-power again, if you close ethereal and then open it again the
CPU-consumption returns to the normal level
