for a few years, we've had a working AS5300 for dial-up connexions. It can stay stable for months without any troubles. But once in a while, it can crash and we need to manually reboot it. When I look in the logs, there is nothing out of the ordinary. Never noticed any warning about an upcoming crash... Recently I've upgraded the Flash RAM (128mo) and the IOS(c5300-jk9s-mz.123-22.bin) and 2 days later it crashed and is now up since... (uptime is 2 days, 11 hours, 21 minutes)
Any pointers to where I might start looking or any kind of help would be greatly appreciated.
My actual config is attached.
