My bad - I added the format string to get a slightly different traceback below (as I explained to Frank Filz, I originally had the call you suggest without errstr, and got pretty much the same segfault).

I noticed that 1) this takes place very early in the starting of ganesha.nfsd, and 2) there's nothing in the log file yet, so perhaps logging hasn't been set up yet? -Jeff On 7/24/20, 8:07 AM, "Becker, Jeffrey C.
