Yes.. this was fixed back in May.  What do you mean by "first test repeat lock" ?  Which pcap did you test on which bro version?

[jazoff at bro-test tmp]$ bro --version
bro version 2.5-beta

[jazoff at bro-test tmp]$ time bro -r bro241lock.pcap
1243601416.209199 warning in /usr/local/bro/share/bro/base/misc/find-checksum-offloading.bro, line 54: Your trace file likely has invalid IP checksums, most likely from NIC checksum offloading.  By default, packets with invalid checksums are discarded by Bro unless using the -C command-line option or toggling the 'ignore_checksums' variable.  Alternatively, disable checksum offloading by the network adapter to ensure Bro analyzes the actual checksums that are transmitted.
