Has anybody seen the following weird issue?
A switch 3750G can't be accessed via console port, the error message "
INSUFFICIENT MEMORY, TRY AGAIN LATER"
if accessed via SSH, it says "OPERATION TIMED OUT"
If accessed via CiscoWorks DFM, the alert showed "INSUFFICIENTFREEMEMORY"
Telnet is blocked. All switch functionalities are fine (including L3 fucntionality).
I don't think it is hardware issue. It looks like software issue(virus? IOS?) Anybody got any idea?
Your reply is appreciated.
This situation is not related to exec-timeout and configuring exec-timeout would not fix it - especially since you are not currently able to get access to the switch to get into configuration mode. While I believe that exec-timeout on vty ports to control remote access sessions is a very good idea, it is separate from your current issue.
As I commented in my reply in the WAN Routing and Switching forum, I suspect that your issue is related to a memory leak. I do not know a way to fix it other than a reload. As long as the switch continue to forward normally you have some flexibility about when to schedule the reload. I would be somewhat concerned that if the memory consumption gets worse that it might begin to impact normal forwarding and need an immediate reload.
