Your tracefile has bad checksums.  Either fix the checksums or use the -C command line flag to ignore checksums.

You can leave out most of this command line.  This should work fine:

bro -r 213.pcap 

BroControl runs with all of those extra args to add various functionality that you don't need to worry about when you're just looking to analyze a tracefile.
