They pretty much should indeed be generated for every received packet,
other than corner-case exceptions such as bad packet headers, or fragments
(there are a number of these).  What I suspect is happening is that
the traffic you're interested in isn't matching the packet-capture filter,
so it's not being looked at in the first place.  The way to check this
is to invoke bro using "-f tcp" to set the capture filter to all TCP packets.
