I have an 877 ADSL router at home and I think I am hitting a resource/memory limitation. It is running 12.2(15)T4 Advanced IP Services and has 128MB of DRAM.
Yesterday I couldn't telnet (or SSH) to it (connection refused). Today I can telnet to it but when I type 'show run' there is no output, 'show start' shows me the saved config OK. It hasn't been rebooted, however I think rebooting it will fix it for the time being. It is however operating OK and all other 'show' commands seem to work. The only thing I can think of is I have done several large downloads over the last few days (some torrents and some just HTTP downloads).
Any ideas before I reboot it?
