memory free low-watermark processor

[patrickcyb]

On our C8300-1N1S-4T2X (17.12.04a), the "memory free low-watermark processor" config line keeps changing.

This behavioour triggers rancid backups every day (since the byte value changed) and our "router has no write" script (since its visible in show archive config difference). Furthermore, it is impossible to manually set the command (it is overwritten). 

Is it possible to either set a fixed value, or remove the line from the running config?

I think that bug is related, but the OPs issue is not fixed.  This value changes in the config now and then. That is the problem that we are seeing and it causes us to think a change has been made on the router, when it actually was not done by us.

I'm seeing this as well, on an 8200 running 17.15.4 (which CSCwe92364 says is a fixed version)

Doing a show run | inc watermark vs a show start | inc watermark returns a different result. No'ing out the command on running makes the two align, but as soon as you do a write again the running changes to a different value.

I'm going to log a TAC case as its making all our routers show compliance faults in DNAC/CCC as it thinks the running config hasn't been saved....
