Description (partial)

Host systems which are using FCoE storage may start experiencing  slowness and over time total loss of storage connectivity due to exchange resources  used on firmware  side may start leaking as a result of qerrors which are not getting processed in time.

Un-grace full host reboots due to power failure or user action when Write IO is  in progress may result in Qerrors.
Any PCIe errors or internal bus errors (transient in nature) during DMA operations related to write IOs would result in exchange WQ errors.
