BB Credit Zero on none ISL ports ?


I have a small fabric (3 switches per fabric all Brocade 5000s), I am seeing "Time BB credit zero" errors increasing on a port which is directly connected to a host, as I understood it, BB credits were only used across ISLs ?

What could be causing this BB credit loss ? would a bad fibre link be causing this ? (Host reports errors when at 4Gbps but seems happier at 2Gbps).

Thanks for your help
