Hello,
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
Did anybody else encounter this problem and is there a work-around?
An experience I made using Ethereal: when you stop the capture, Ethereal
processes the received data and during this process it seems to "fall
sleep" several times. This is because Ethereal tries to resolve all IP
addresses through DNS and if you have a private network this will not
succeed, the DNS process will then be terminated by a timeout and this
can take some time. It can be omitted if you disable the name resolution
options (in the capture settings).
