I cannot telnet to one of my router, the error messages is Low on Memory, try again later.I can telnet the other router and ping each other. The router which I have a problem was connected to 6 serial interfaces connected via leased line and 1 E1 connected via fiber optic. I have two another E1 controller which connected to MD110. I cannot connect to the other sites due to this error. Is there anybody who experience this problem? Please advice how can access this router and how I can fix this problem.
Well, its going to be difficult if not impossible to fix the "problem" now. If possible, you should get someone at the site with the router in question to see if they can get in via console and if they can, do some basic show memory commands for troubleshooting and save the output.
You will have to somehow decrease the load on your router, you can do that by bringing down a link or more, I know it will bring down your services for a while but I don't think there is another alternative, once the load is down, you can then telnet ur router, plz note that low on memory means severe performance degradation, add more memory to router, decrease its laod by shifting some links to another spare router, plz do check cisco documentation regards troubleshooting high load or excessive memory usage.
