     No, I haven't. At the moment, I'm fairly sure that there's no
     problem in the connection or in the communication between the M10
     and the 6509.

     Such a thing would be really nice to have. I have to start
     looking around whether anyone here sells the splitters.

     Native.

     The only one reporting the errors is the Cat and the errors
     appear once in a few hours. M10 has nothing to complain about
     (well, there's a tiny memory leak, but the box doesn't complain
     about it yet...)

     
     This really is a Cisco issue more than a Juniper one

     Thanks to all who helped.

     Cheers,
