Module specific reason codes (yyyy = 4000

A yyyy value in the range 4000 to 4FFF indicates that the reason code is a module specific reason code, whose meaning can vary, depending on which NFS module issued it.

Table 1 shows the yyyy values that can occur when the xx value is 12 (module GFSCVNAT) and their meanings:

Table 1. Reason codes for module GFSCVNAT (xx = 12)
