Hi,

Guy,   Is there a way to know when the machine will run out of memory?
(for example running Tshark for 1 hour = leak XMB.. or something like
that.)

Tshark doesn't leaking memory, if it did that would be in error. What it
does do is build up context, which expands in time, depending on the
traffic captured. Therefore also no consumption rate can be defined.

tcpdump is not part of the wireshark package, is there any
solution for long packet capture with wireshark package?

As stated, use dumpcap.
All this information can be read on the Wiki:

Thanks,
Jaap

We have been trying to do a long running capture and we cannot keep
Wireshark up and running. WS is up to date. We are monitoring 1 port and
writing out 100MB files. Each file is filled in a 2-4 hours. WS will not
stay up forever. It dies every so often. We are trying a larger buffer
size.

Are there any known issues?

Other than "dissecting packets consumes memory, so if you use Wireshark
or TShark to do a long running capture, you will eventually run out of
memory and Wireshark/TShark will fail"?

The way to avoid that issue is not to use Wireshark or TShark to do
long-running captures, and to use dumpcap instead.
