6450 stack w/8030n issues?

[todd_adamson]

I'm working on setting up a 4 unit stack of ICX 6450-48s.  Firmware installed is 8.0.3n - Routing.  I am getting a continuous stream of the following entries to the console port:

T=17h5m20.1: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h5m57.7: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h7m59.8: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,
T=17h8m9.4: 1/2/1 goes down. delete direction 0, trigger election
T=17h11m20.3: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-up, ,
T=17h13m56.9: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,
T=17h17m9.5: 1/2/1 goes down. delete direction 0, trigger election
T=17h17m38.5: Election, was active, no change, ID=1, pri=128, 4U(1-4), A=u1, nbr#=3 3, reason: u2: port-dw, ,

In addition the input errors and CRC numbers are steadily increasing.

I'm using the standard 1m stacking cables.

Does anyone know what might be happening?  Is there a different version of firmware (earlier/later) that I should be using instead?

Any help is appreciated.

If a stack port flaps or loses communication, it will trigger an election. You need to clean up the stack ports if you are seeing errors. What is the media type? Have you tried other cables? Can you gather the following:

show stack
show stat e 1/2/1 e 1/2/3 e 2/2/1 e 2/2/3 (assuming these are the stack ports)
dm statistic
show media
show log

[todd_adamson]

dm statistic shows the following info for the relevant stack ports:
123-0-0-0(1/2/1)
31-0-0-0(1/2/3)
3-0-0-0(2/2/1)
3-0-0-0(2/2/3)
5-0-0-0(3/2/1)

Looks like layer 1 port flaps to me. Left most column is layer 1 (physical) transitions:

123-0-0-0(1/2/1) 
31-0-0-0(1/2/3)

Have you tried other cables?

[todd_adamson]

I only have the 4.  One of my future troubleshooting steps was to try them one at a time.  I'll try it sooner rather than later and report the results.
