Routerboard network lockups and timesout at random...

RouterOS General
1

Hello Folks!

I have been using MT for a couple of years now, as start with RouterOS4.11 life become a nightmare, so we had to rollback all our routerboards (RB333,RB600,RB600A,RIC522C,RB450G,RB750) to 4.10 again, things become better.

RouterOS 4.11 did not work at all, everything were just rebooting all the time and whole network collapsed.

After rollback, we still experience timesouts and lockups in the network, kicking people out of Citrix sessions and putty sessions when it is as most worse. This can happen several times per day as most worse.

There is absolutely no problems with our dual internet connections, if bypassing MT router problem is not there anymore.

I have tried everyting I know now, there is nothing in logs anywhere. I do netwatch ping to try monitoring this, with various progress, I do not hit all the lockups since I ping 1 time per minute.

Is there anyone who have faced this problem, how did you solve it ?

Hello Folks!

I did update to RouterOS 4.13 with success, and the bomb went away.
From RouterOS 4.13 I lifted to 4.16 with success and now in track again.

I did head firmware problems on 4 of 15 devices, cpu-frequency was lost and some else errors to, setting them back solved the problems in 3 devices.

The 4 device needed to be resetted at power on, and then set back cpu-frequency + fw update and last routeros.

Then all network is stable again, exept some rb411 boards reboot themself at slow random intervals.
