Best thing to do now is an upgrade to 12.2.33-SRE12 MD since you are running SRE3. 

crashinfo file is more for TAC engineers. I see only tracebacks and "possible Software failure" messages.

Do you have CoPP enabled and what about CPU usage when traffic is around 400Mbit/s?

thank you for your prompt help.
Copp is not enabled and the CPU usage was around 10%. i will upgrade to 12.2.33-SRE12 MD and check if this will fix the issue.
