I have a router (Power Edge 732) running MPLS in 4 Vlan interfaces. it was working great but a few days ago when I add the #4 LDP Interface to the MPLS Cloud, the router start to rebooting constantly (The router was rebooted without a proper shutdown) I change the router for other same (PE 732) and this is not rebooting but the performance in winbox is to bad. and I see TX errors only in the vpls interfaces.

Is not MTU issue I check that all MPLS interface are set 1530 the circuit that are using this MPLS look perfect in ping test or bandwidth-test but still the problem with winbox. by telnet work perfect.

When I disable the LDP Interface fix the problem and the router work great again.

somebody has see a problem like this??
