so I am trying to resolve one weird issue we're seeing on some of our routers last 2-3 weeks. Whenever someone changes some settings there (e.g. adds things to addresslist, changes e-mail settings, changes queues, etc), sometimes the changes just return back without any notice (which causes a lot of problems).
Have you seen something like this before? Do you have any idea how to debug this issue? To me, it seems like the configuration is not getting saved, works for some time from some kind of cache, and then resets to whatever was saved before, but replacing the disk in the router didn't help.
(there's no message in log, entries in system/history seem to be okay, but the configuration is reset back. also, I've triple checked that I was not in Safe mode.)
