new 32-bit binary for nssm.exe, upgrading from the previous 2.16.
Has some bug fixes, see http://nssm.cc/changelog.
Driving impetus to upgrade was "Silently ignore INTERROGATE control.",
on win2012 nssm spews ~30 event log messages per minute.
Tested by stopping windows minion, replacing nssm.exe, and restarting.
NOTE: This is a potential change --- I haven't actually gotten a
test environment to try this out.
This adds a configuration option to the minion,
`acceptance_wait_time_max', that if set changes the acceptance
wait loop to add `acceptance_wait_time' seconds to the wait between
each iteration, up to this maximum value.
POTENTIAL FIX: Issue #5813
