Hello ,

 

I have router 2911

 

Cisco IOS Software, C2900 Software (C2900-UNIVERSALK9-M), Version 15.4(3)M3, RELEASE SOFTWARE (fc2)

 

After an unexpected reboot it says:

 

System returned to ROM by bus error at PC 0x357F0454

 

before reset the router we can't got incoming/outgoing calls .

 

After we made reset ,the problem was solved.

 

we need to know why the router crashed?

 

thanks

Most likely due to a memory leak.
Recommend to upgrade the IOS.
