Hi

You dont seem to have enough buffer space which is resulting with this error, if you can afford a reboot try rebooting the router to over come the same.

regds

Any workaround by using the command

set buffers <>

or any other workaround instead of rebooting the router

Regards,

Ranjit

The error message you posted seems to be incomplete.

Aug  2 11:40:38.954: %TCP-6-NOBUFF: TTY0, no buffer available -Process= "", ipl= 0,

There should be a process name. Are you seeing any other type of error messages? What changes did you make prior to noticing these messages?

Hi,

We are getting logs with reference to BGP process

We also tried changing the Small buffers, Middle buffers, big buffers, very big buffers, large buffers & hugh buffers but with no luck.

Tried to adjust the permanent buffers but again the same results.

Kindly reply,

Looks like a memory leak in the Big buffers. Could be due to CSCsg76611
