My question:
Is there a known limit on the number of packets that wireshark can deal with in a single file?
The number of packets that Wireshark (or, I suspect, any network 
analyzer) can deal with is limited; due to a number of factors, the GUI 
widget used to implement the packet list display being one of them (it 
allocates a string for the text value in every column, which eats a lot 
of memory), Wireshark's limit might be lower than some other analyzers.
This is not a limit saying something such as "Wireshark can't read more 
than 1,227,399 packets"; the point at which it'd run out of memory 
depends on the contents of the packets.
