Due to this issue, Rational(seconds, 86400) is not called and some plugins doesn't start from the second time.

e.g retry_delay is critical.

origin-server/node-util/sbin/oo-watchman

Line 110 in 73197c2

@retry_delay = seconds.instance_of?(Rational) ? seconds : Rational(seconds, 86400)

Workaround is setting the default values in /etc/sysconfig/watchman.
