Subject How are router checks scheduled?
Date Mon, 10 Apr 2017 21:53:40 GMT
According to my management server logs, some of the period checks are getting kicked off twice
at the same time.  The CheckRouterTask is kicked off every 30-seconds, but each time it is
ran, it is ran twice at the same second...  See logs below for example:

2017-04-10 21:48:12,879 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-5f7bc584)
(logid:4d5b1031) Found 10 routers to update status.

2017-04-10 21:49:12,928 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-d58842d5)

How is this scheduled/kicked off?  I am debugging some site-to-site VPN alert problems, and
they seem to be related to a race condition due to the "CheckRouterTask" be kicked off two
at a time.

Thanks
Sean
