4048-ON switch continues to remove admin account configuration

I have a 4048-ON switch that I have configured the admin account on that seems to lose its own password after a couple weeks of operation.  Have tried reboots,  resetting the password,  and even a full new OS install with no change to the admin account getting locked out.

To clarify, I have reset the password, saved the config, and then attempted to SSH to the admin account immediately after on more than 1 4048 and it just appears that this particular switch is doing this.

Hi,

 

What is the current firmware of the switch?

 

After you have reconfigured, you will have access right? Could you run a #terminal length 0, #show tech-support, #show logging to check if there are any errors or to identify the root cause.

Hi,

 

Let's get the switch up to the latest to try to resolve it. I spoke to the L2 and may have a though might be a corrupted Linux kernel. 

 

If you do have a running config and startup config in the switch, back up it.

 

Get into ONIE rescue mode, update onie-updater and onie-firmware then os10.5.5.6.
