Running snort and barnyard with 3 sniffing interfaces

I need a sanity check here, as I'm having a little problem with barnyard. I have a CentOS 5 system with the most recent version of snort and barnyard. The system has 4 interfaces: one is the management interface while the other 3 are the sniffing interfaces with no IP and SPANed on a Cisco switch on 3 different VLANs. Snort on each of the different sniffing interfaces has a different start up script and consequently generates different snort.alert and snort.log files. This all seems to be working correctly. When I set up barnyard, I've done something similar: there are three different instances of barnyard for each log pair, and consequently each runs with a different waldo, pid file, and configuration configured. They all have "-d /var/log/snort -f snort.log" configured. Here's the problem. I get a fair amount of hits on the public snort sniffing interface; however, barnyard doesn't add anything to the dump.log file. The other instances of barnyard for the other interfaces appear to dump info into the dump.log file. This may be of interest, but does anyone see anything I've done wrong? root 9536 18.8 3.6 226044 145480 ?
