svn commit: r344276 - head/sys/rpc/rpcsec_gss

[Edward Tomasz Napierala]

Author: trasz
Date: Tue Feb 19 11:07:02 2019
New Revision: 344276
URL: https://svnweb.freebsd.org/changeset/base/344276

Log:
  Bump the default kern.rpc.gss.client_max from 128 to 1024.
  
  The old value resulted in bad performance, with high kernel
  and gssd(8) load, with more than ~64 clients; it also triggered
  crashes, which are to be fixed by a different patch.
