Hi, sorry for my bad English.

I have 2 licenses Microtik (Level 6) installed on 2 pcs, and on both machines the same thing happens.

Ips routes stop working and the router loses connectivity over IP, I can only access using the MAC.

I have recorded a screencast that you may see exactly what is happening in my router.

Please, I tried 1000 things, I searched on google, this forum and find nothing related

any guru can help me?
Thanks

looks like the routing program is having a problem. make a supout.rif file and send to support

I can not create the supout.rif file, the router can not export the (ip route) settings correctly and stays "frozen".

just type "/system sup-out" and wait for a few hours, it will finish eventually

ok, I got it, I will send to technical support.

Thanks for the help

wait for a few hours

You are not alone in this issue. I have been experiencing the same thing. For me, it is triggered by changes made to OSPF on any adjacent routers. It even happens sometimes when the physical interface goes up and down. I am working with MikroTik support on this one.

Tech support guys told me:

"[...]
Cause of the crash is frequent interface status changes. This bug is fixed in v4.6, wait for next RouterOS release.
[...]"

I'm waiting impatiently for this update, but it's good to know they have controlled this bug.
