Before to start a make a statsclear on the fabric of my laboratory. This fabric is used only by me. Then, i copy some files, about 10MB, to a san volume. After this copy, i use a portstatsshow command on used ports. And some of them have a not null tim_txcrd_z. For me the time is the time that a port can not transmit frames due to a transmit buffer-to-buffer credit of zero. Come you confirm that it is not normal ? If you agree, i don't know how to fix this.
Help is welcome.

More informations :
I'm not in a long distance case. All my fibers are 2 meters long.
I have a not null tim_txcrd_z count on following ports :
- ISL (not trunkated) : some times only on one side of the ISL, other times on both side of the ISL.
- 1 port of the storage
I have a null tim_txcrd_z count on ports used by server.
Is it possible that this count is not null due to a physical issue on fiber ?
