"T" train IOS is known as the "technology" train.  Some of us call it "trouble".  The objective of the "T" train is for new features to be introduced to the IOS.  New "features" also means bugs, which can vary from configurations to configurations and one of the main causes for appliance crashes. 

 

Generally speaking, the consensus among some of us is this:  If the router(s) is/are running "T" train, then don't be surprised to see the appliance(s) crash very often.  


The "M" train is known for stability purposes and this the reason why I'm recommending you try loading.

Can you post the complete output to the command "sh version"?

Of course, look at this attached file.

Thank You so much Leo

Ok, just as suspected.  The IOS is a "T" train.  Try upgrading the IOS into something more stable, like an "M" train.

ok, i will upgrade the IOS, can you tell me what happen, why does this router reload?, Maybe become to increase the CPU usage, become to run any process?... please, i jus want to know what can happen here.

Thank You So Much

thank you So Much..

If you can Explain Me in more details what could Happen here about that bug, i will thank you a lot.

I'm no Cisco staff.  So decoding Tracebacks and system crashes is going to be the job of Cisco TAC.
