"Signal 6" is OutOfMemoryError, so TShark just ran out of memory.  That's why
it's hard to reproduce - you have to capture for long enough, or read a big
enough capture file, so that you run out of memory, and the memory requirements
aren't based on the size of the file, it's based on a number of things,
including the amount of packet reassembly done.

The problem is that we don't catch OutOfMemoryError at a sufficiently high
level, and report "sorry, not enough memory" and clean up appropriately (where
"appropriately" would be different in different cases, e.g. TShark should just
stop capturing/reading, report "sorry, not enough memory", and quit, while
Wireshark should close the file and free up everything it can, and then pop up
a message box saying "sorry, not enough memory" (which it won't be able to do
until there *is* enough memory).
