Author: pfg Date: Fri Jun 29 18:49:14 2012 New Revision: 237817 URL: http://svn.freebsd.org/changeset/base/237817 Log: Bump dtrace_helper_actions_max from 32 to 128 Dave Pacheco from Joyent (and Dtrace.org) bumped the cap to 1024 but, according to his blog, 128 is the recommended minimum. For now bump it safely to 128 although we may have to bump it further if there is demand in the future.
