i have a couple 2501's holding up a T1 line. static routing config, no RIP/OSPF/BGP, no httpd. router A is Version 11.0(16) router B is Version 11.1(5) starting saturday night, i noticed that snmp queries were failing to one or both of the routers at various points. i tried to log into the routers, but telnet was failing. using the console access to one of the units, i found that memory was exhausted.
This is an old IOS bug affecting 2500s. Not sure of the range of IOS images with the bug present. I had to work on a massive field recall a couple years ago (engineering-issued, not Cisco-issued) to upgrade the flash in these things so that we could slap a 12.x IOS on them. -jeff -- Jeff Gehlbach, Concord Communications <jgehlbach () concord com> Senior Professional Services Consultant, Atlanta ph. 770.384.0184 fax 770.384.0183
