Buffer Error on 3.11

Hardware MikroTik hardware general

Every couple of weeks one or more of my RB333s running 3.11 will quit passing IP traffic. When it does, I can still MAC telnet in, but can not do anything via IP. This morning the offending unit had nothing in the log. When I tried to ping from it I got the following:

[admin@RouterName] > ping 10.0.0.34                                             
105 (No buffer space available)
105 (No buffer space available)
2 packets transmitted, 0 packets received, 100% packet loss

What does this mean and how can I keep my routers from going down?

Hi,

did you tried to log in with other computers?

I had similar problems with my computer. I had a virus and I found something extrange in netstat -an. Lots of connections in port 10000.

I reinstall my system and problem solved.

I could not log in via IP from my computer or from several RB routers.

log into it from serial console, and check the traffic. maybe you are being attacked, or there is a virused PC in your network, as Ibersystems said

Console is a problem as customers are down and the routers are at towers, but as I said, I can MAC telnet in. So getting in isn’t a problem. I will try to check traffic next time it occurs.

This has occurred on multiple routers at about the same time. The routers are not located such that any one customer routes traffic through all of them.

The problem has only occurred on RB333 routers running V3.9 or 3.11. It has not occured on my RB532s running 2.9.49 nor the RB600 running 3.11.

Seems to take about 2 weeks to recur.
