OK, this sounds a bit strange, but for some reason this just started happening today on one of my routers. I set the logging buffered size, then a few minutes later, i show log and it is reset to 4096.
No one else is logged into the router. I have run with a large logging buffer for a few weeks and this just started happening today.
Any ideas on what might be causing this? BTW, whenever the logging buffer size is reset the the logs are cleared, so it is hard to see what is causing the change.
