hi,

what's your telnet timeout config?

could you post show run telnet?

Hi ,

Thanks for your reply.  I think this shouldn't be telnet timeout issue .

 

My telnet timeout config "telnet timeout 300"

Hi,

Can you get these outputs:-

show resource usage

show process cpu-hog

show process

show ver

Thanks and Regards,

Is there anyone can help me ?

 

Thank you !

Hi,

I went through the outputs and the only thing i see which might be related would be the denied connections on the ASA evice.

Rest all the things are fine. I also see that the ASA device is running a very old and unstable code :- 8.21 , so i would recommend an upgrade to the 8.2.5 if possible the latest interim and i think that should take care of this issue.

Thanks and Regards,
