Continuous BUG 1500 errors on CS1000

[CheriGorski]

Hi,
Anyone have an idea as to what BUG 1500 errors are related to? The Nortel description is vague and doesn't tell me much. Several of these errors are being generated per second starting today. Last night we cut our Lyrix voice mail servers over to a new network and assigned new IP addresses. They are communicating between eachother fine using the new network connections but now I have all of these BUGs in the switch. Another possible cause is the Cisco IP phones we've been rolling out and creating CDPs for in the Nortel so the two systems can dial one another. We've been growing the Cisco IP environment for months now and never got these errors, so I don't think that's the cause.
Here's a screen shot and below the Nortel explanation of this BUG which did not clear things up much for me. Any suggestions would be greatly appreciated! Thanks.

And these numbers after the error don't correlate to any TNs, DNs, MAC addresses, nothing that I can identify a relationship to.
