SSTP crashed RouterOS

Hi, im using RB133 with RouterOS 5.0 beta5. After i upgraded to the 5.0 rc6, SSTP server crashed RouterOS after i did vpn connection. Here is the first line in the log: System rebooted because of kernel failure.

Everything works perfectly when i did downgrade to the 5.0 beta5.

Any idea, suggestions?
