I've tried to find the limit where tshark is not usable (for us) and it's
around 460 ip addresses per device (440 worked fine). I've straced tshark and
its somehow stuck in opening eth0 device due to the huge number of ip
addresses. Strace output attached, sorry for the big file.

Am I assuming correctly that tshark tries to open/bind to eth0 for every ip
address it finds on it? (I'm not familiar with pcap programming.)

There's an i/o error at the start of gdb, it seems that it's trying to find
linux-gate.so.1 which is some glibc internals. Is this gdb output okay for you
or need some more/specific stuff?
