Callback slot table overflowed

Is this bad?

Jan 19 21:53:27 pdsi7 kernel: Callback slot table overflowed

All I can tell from the code is that xprt_alloc_bc_request() failed, and the slots are "preallocated during the backchannel setup". Is there a hard limit on these slots? Where is it set?

This shouldn't happen as the slot table size is negotiated on session establishment. Currently, the client support NFS41_BC_MIN_CALLBACKS (1) request(s)

Examine the CREATE_SESSION that created the fore channel, the back channel limits are set there. Also note that since this is the back channel server setting the CREATE_SESSION backchannel attributes that the back channel client (e.g. the server) can not increase any of the limits.
