We have several stacks of 3750 switches where this problem is occurring. All of the switches are running IOS version 12.2(50)SE3. (Yes, I know it's old.)
We're seeing inconsistency in how the stack reports members when issuing the following commands:
show switch
show version
show inventory
Not all members are showing up in the output of the "show version" and "show inventory" commands. For example:
HUNTI-WV-WDAC03#sh switch
H/W Current
Switch# Role Mac Address Priority Version State

1 Member 108c.cff2.ea00 15 0 Ready
2 Member 8cb6.4f0a.a600 1 0 Ready
*3 Master 8cb6.4f0a.9c00 1 0 Ready
(all three switches in stack are displayed)
HUNTI-WV-WDAC03#sh version

Has anyone else seen these symptoms? I searched the bug toolkit and was unable to find a match.

It sounds like an IOS bug.
I know you've searched for the bug in the toolkit but NOT ALL bugs are published. There are some internal bugs that are left out.

I have the same problem. The problem started two days ago but in only one of the cisco 3750 I own. Both switches has the same ios version same settings etc etc.

Our on-site Cisco engineer said that this was a bug, and recommended that we upgrade IOS. Which we did. I haven't seen the problem since. We upgraded to 12.2(55)SE7
