Re: 6.21rc22 to trigger kernel panic?

Ok, we will have to wait until after hours again to repeat this exercise. There is only 60 seconds between crashes so I need to try to capture everything fast, upload the stable version and downgrade. I will try and email support when done.

6.21rc22 to trigger kernel panic?

I upgraded a CCR from 6.13 to 6.21rc22 and the router started rebooting on its own every minute. Was able to see in the logs that the router rebooted itself due to a kernel error but had to quickly go back to a stable version (now 6.20) as it was a production router.

Anyone seen this on rc 22?

graphing disk utilization

When we check the button 'Store on Disk' in the graphing option, I am wondering if there is some limit and auto clean up that the system does, so that the graphs don't consume the entire disk after awhile? Or do we need to do the clean up ourselves with some script. If we need to do it, how do we cl...

Re: CCR1036 problems

Was there any follow up to this? We are passing 300mbit on a CCR with 6.10 and getting many reports about SSL timing out, etc. No issues with our x86 routers on a different network passing the same amount.

Re: CLOUD CORE ROUTER

Actually this happens to us on the x86 RouterMax. We run the latest firmware and ever since we got these, and if you change an IP or disconnect a device and connect it again, it won't re-establish layer 3 and only a reboot will fix it. OSPF can take a few minutes to re-distribute. The port flapping ...

Re: CLOUD CORE ROUTER

Using firmware 6.6 on a CC and it's still flapping. We disabled LCD and SNMP and it's a bit better. What we noticed is that these conditions will cause flaps: 1. Over 20,000 pps per interface 2. Over 300mbit per interface 3. SNMP 4. OSPF changes It's almost like there is a capacity limit that is eit...

Same here. As soon as we cross 300mbit, it starts to flap non stop. Does not happen on x86 platform. Using 6.6 and it is worse than 6.5.

Re: auto redirect home page to /graphs

Well, our situation is slightly different. We are using a board in bridge mode infront of every customers.

So while we can capture the customer now and redirect them to the /graphs of the bridge ahead of their network, it's not easy to mask the IP and make it friendly.
