Power Router 732 Spontanious Rebooting

RouterOS General
1

Hi Everyone,

We have a very unusual problem which hasn’t been fixed and I´m hoping someone had a idea of a fix. Here is the issue:

We have 2 PowerRouters and both are doing the same thing. They spontaneously reboot without warning and the only error message we get in the logs is that it has shutdown unexpectedly.

We have many clients connecting to our PowerRouter, all via L2TP with ADSL Routers. We have to use RouterOs V4.6 and above as that allows unlimited PIMS instead of the standard 32. Each customer has a PIM, and we have more or less 800 people on 1 power router. We have tried all RouterOs´s including Beta. It has the latest firmware updates and currently running RouterOs 4.10.

We have 2 power routers, and swapped them out, and they both do the same thing. It may last 24 hours, or only a hour.

We have disabled hyper threading, and we are running 1 CPU, but no results.

We also have a RB1000 temporary as a failover alongside and this works great with no issues.

Does anyone have any ideas? We have had lots of people look at this for 8 weeks and urgently need a resolution and hopefully you guys are our answer :wink:

Mikrotik have our spout files and logs.

Thankyou

Ben

X86 Hardware requirement as per the scenario

did you run a memtest? is it overheating?

rb1000 isnt a x86 platform, i wonder if its just something to do with the x86 code vs ppc/mips.

Hi,

Sorry for my delay is replying. We have a Mikrotik Guru and he said it isnt that (sorry to be vague but I am not a Mikrotik Expert)

The power Router goes down most nights at around 9pm?
Also, if we put over 200 l2tp connections instantly over to the power router, it crashes and if the power router has over 700 l2tp connections it also crashes.
If we manually disconnect over 200 l2tp connections the power router crashes too.

We have changed the RAM but no resolve.

Does this extra info help?

Thanks

Ben

do you use simple queue for l2tp tunnel ?

Hi all
Yes the setup are using the simple queue.

Hi,

Thankyou for your reply,

We have removed our radius bandwidth limit therefore removing l2tp clients from the “simple queue”.

But unfortunatly the power router 732 rebooted again. Maybe a co-incidence but again at at 9pm… Even though no scripts that I could see were running (not sure if that is relevant as not always 9pm but a lot of the time)

Even if you select 20 l2tp clients in active connections and disconnect them, the router also reboots unexpectedly.

Hope this helps…???

Thanks All

Ben

you should contact support with your supout.rif file, make the file immediately after that 9PM reboot

we have a open ticket!

hello
what’s up with your issue after all?

Hiya,

We are having some very strange issues,

We have an RB1000, a PowerRouter and a Dell Server (forgotten the model but a very high spec)

We are running L2TP connections Via a BGP. Each connection has its own PIM.

We stream multicast from another RB1000 Via a VPLS to the BGP then on to the three routers.

Then any L2TP connection that requests a stream via an IGMP Join receives a stream.

2 problems:

  1. The Power router reboots every couple of days and the Dell stays up for the most of a few minutes every 8 hrs. or so.
  2. When the power router has more than 30ish connection to a single PIM MFC Stream then the quality across all channels is very very poor

I will be attempting to stabilise the Dell by disabling various network adapters as this seem to work last time.

Any Help is appreciated.

Regards

IB
