I have a x86 router running 3.13 that is currently locking up every 5-8 days.
The router stops passing traffic, OSPF & BGP both stop connecting to neighbors & peers.
I am able to log into the console and run commands, I created sup-out for Mikrotik and also looked at the log before rebooting this time.
The log file showed these errors:
17:23:54 route,ospf,error Cannot send packet: sendmsg failed!
17:23:54 route,ospf,error error=No buffer space available
17:23:57 route,bgp,info Failed to open TCP connection: Network is unreachable
17:23:57 route,bgp,info RemoteAddress=x.x.x.x
Has anyone seen these errors? Does 3.14 fix something to help with this?
I got the same message right before reboot. Can anybody help? Firewall is ok, it doesn’t drop ospf packets, and ip traffic flow is disabled. I’m running v3.28 on RB600.
Make sure that you use the newest firmware (routerboot version) for the Rb600 as it had a fix for the DDR about six months ago. Before the fix, if the board was hot, it would reboot every 24 hours of less.
I had an x86 router do this earlier yesterday. the router was still running locally, but no network connectivity was working anymore. Any pings or attempts to connect to anything gave me the buffer out of space message. This was running 3.25 with traffic-flow enabled pretty recently. i have disabled it and will see if it keeps happening. I took a supout while it was in this state and will try to get it to them.
Sorry but it’s not “the same problem”. They are completely unrelated.
You get “Operation not permitted” error when you have blocked OSPF packets in your firewall.
You get “No buffer space available” error when the packet cannot be sent because the memory buffer space allocated for the sending socket is exhausted. That may happen when there is some problem with the interface (e.g. perhaps wireless interface in not associated state?), or with the driver, or with something else.
