To close the loop on this thread, the issue appears to have been OS/install related; rebuilding the OS on the machine with something different (RHEL 7 rather than Centos 6.6) and the issue no longer manifests.
As an additional oddity, a PCAP taken from the malfunctioning machine had the same filtering issues across multiple platforms and tcpdump versions.
