One suggestion and I'm talking Brocade here. Presumably Cisco have something similar but I'm not familiar with those. Are we using multiple switches here and are there ISLs between them?
If so, an ISL can only go 10km and then you should have the Extended Fabric License. This allows you to allocate the extra buffer credits to the ISLs that are required to use the full bandwidth. Even 10km needs extra buffer credits allocating (it's not the default) but that support is built into the basic license.
