Random restart asus routers temporary fix

Hi.
I was contact to Asus support with my problem (random restart) and we found problem. My router sometime restart when send email (aiprotection).
If You use this feature then You can check this using telnet, simply paste this command and check

rc rc_service send_confirm_mail

for my router this command executes about 3-4 second I paste this command few times, and after 4 or 5 my router restart.
For now i disable send email in router setup, and router work stable.
