I have this problem too. After upgrade to 6.28, my CCR1036 still working fine at 7-10 days whithout new configuring. Then i have this problem (2 times in 1 day). Please help.

Hi,

Any update for this problems?

Thanks

As a data point, I've not seen this behavior with my five CCR1036 units on various firmware revisions.

"RouterOS CCR1036-12G-4S",""6.30.4""
"RouterOS CCR1036-12G-4S",""6.18""
"RouterOS CCR1036-12G-4S",""6.24""
"RouterOS CCR1036-12G-4S",""6.30.4""
"RouterOS CCR1036-12G-4S",""6.32.3""

What are the connections into the boxes with which you are seeing the described problems? Is it a wireless link? A 3 meter ethernet cable in an air conditioned room? Is there a network switch in the middle?

In my case, my ccr is connected to some other router and switch. connection using ethernet cable on server room with air conditioned. I have record my desktop to monitor my CCR using winbox to see is there any anomaly traffic or CPU. But, shortly before crash the CPU is normal around 10%.

And when crash, I must to power restart to make it UP again. my box is CCR-1036-12G-4S-EM. I have upgrade to the latest OS 6.34 and it's still happen. Any advice?

Thanks

Open a support ticket with MikroTik. Email support@MikroTik.com what you describe is not normal.

Any Update??

the temporary solution is i must do "hard reboot" and the router will working fine again.
