An unexpected reset on the active supervisor caused a switchover between the active and standby supervisor engines 32 / MSFC 2A
on cisco WS-C6509-E, Cisco IOS Software -s3223_rp Software (s3223_rp-IPSERVICESK9_WAN-M), Version 12.2(33)SXH4.
I used the output interpreter to analyze "show logging" command output and found a possible CSCsl02596 or CSCsg43532 bug, so I tried to find more details with Cisco Bug Toolkit but I did not have success -in the bug toolkit area explained me about the bug, here the post Bug Toolkit is unable to display CSCsg43532 bug details.
I decided to upgrade from SXH4 to SXH6 because I found a traceback at the cras_info files -%ALIGN-1-FATAL, I have attached the crash_info files.
This failure was caused by a software defect ¿?.
