Hi Artyom, I have decoded the crashinfo and you're hitting the following bug: CSCtn68186 - crash on BGP up when 'ip cef accounting non-recursive' is configured
This is fixed in 12.2(53)SG5 and 15.0(2)SG and later releases. Workaround is to disable 'ip cef accounting' which is not supported on the 4500/4900 platform.
