weirdness with Extreme

Has anyone else seen this kind of thing before?
2 Extreme Black Diamond 6804s (ExtremeWare 7.2.0b37) at the core
(active/standby) start to fight over which of them is master for a
particular VLAN. They go back and forth for maybe a minute, and for a
brief period, the master switch seems to fight with itself over which will
cede master status. The log messages indicate either high/low port count,
or high/low priority, for that particular vlan. ESRP then forces access
switches hanging off the cores to flush their forwarding databases. All
activity takes place within a span of just over a minute, then dies.
Extreme doesn't have anything to report yet. Just wondering if anyone has
seen behavior like this in an Extreme environment.
Thanks,
Andy
