When you run Bro from the command line, everything in the trace you
give to an invocation will end up in a single set of logs files inside
the current directory. But if you then restart Bro with a different
trace, these logs will be overwritten with new ones (i.e., Bro won't
append the new data). You'll either need move them away before you
start the new Bro, or you could concanate all your traces into one
pcap stream on stdin and have Bro read from "-" (tcpslice and mergecap
can both do that).
