We've had some weird things with the MX5071 on a particular network.

There must be something on the network that makes the machine freeze.

Only thing you can do at that time is a hard reboot, then the machine works for a few minutes, then freezes again.

Pings are also never constant, always a lot of timeouts or high latency.

Only solution we found is to put it on a different VLAN...


On another site, we had a lot of E7-90 errors...there we found a particular ip address that was doing something, everytime just before the error (in the log files), there we blocked the ip an no errors since then.
