Disappearing BCV's During Meta Expansion!!!!

Hello friends.

I have a strange one. Even EMC is at a loss as to the root cause. During a striped meta expansion, most of my BCV's "disappear" until the expansion is completed. There are 3 BCV's associated with each standard. I have a DMX2, and am running SE 6.4.3. The correct number of STD/BCV pairs shows under symdg list, but if I do a symmir -sid xxxx -g query -mulit, it only shows 5 STD/BCV pairs, until the meta expansion completes (instead of 89)! This is causing service disruption.

Has anyone out there seen this? I'm guessing the SP is getting hammered, and running out of resources to be able to report the status of the symmir query during the expansion. I am wondering if there is a bug in the microcode that is not partitioning SP resources properly to enable other operation (i.e. the expansion takes over). I have seen hot-swap operations take priority and cause establishes to take a LONG time, but never to lose insight into BCV's and prevent any operations.

Any help greatly appreciated.
