Do you have 2 management servers? Simon Weller/615-312-6068

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 21:48:12,932 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-d027ab6f) (logid:1bc50629) Found 10 routers to update status. 2017-04-10 21:48:42,877 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-2c8f4d18) (logid:e9111785) Found 10 routers to update status. 2017-04-10 21:48:42,927 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-1bfd5351) (logid:ad0f95ef) Found 10 routers to update status. 2017-04-10 21:49:12,874 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-ede0d2bb) (logid:6f244423) Found 10 routers to update status. 2017-04-10 21:49:12,928 DEBUG [c.c.n.r.VirtualNetworkApplianceManagerImpl] (RouterStatusMonitor-1:ctx-d58842d5) (logid:8442d73c) Found 10 routers to update status. 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
