Hello,
I have a few Cisco 3G routers configured across Europe which VPN back to an ASA and occasionally 3G will drop and sometimes someone will power-cycle the router which loses the log history so I started to use logging persistent url flash: to save the logs to flash, but I don't think it is working properly or the log space is getting used up as it currently only has 2 days worth of syslog info in the flash and I need it much longer so I can see what the 3G router is trying to do when offline.
I have added a reachability SLA on another site that pings Google and when it can't after so many attempts it does a "shut" no "no shut" on the cellular interface which has helped with reliability.
Anyway here is the loging and flash info, maybe you can see an issue?

Maybe my sizing's are all wrong (never been too good at judging them)?
Thanks
