Just FYI, we're now in contact with foundry directly and opened a case regarding this issue.<br>By now it seems to be a memory allocation problem in MLX as well as in XMR series in combination with many bgp sessions.<br>
As far as I know they try to fix that bug in the ironware 39xx.<br>Until then we can bypass the problem by using a XMR (with 2gb ram) instead of the MLX (1gb).<br>
