Hi Anthony, I am seeing the same effect on my installations.
When that problem occurs, I also get repeated entries in icinga2.log: [2017-10-24 01:15:28 +0000] information/WorkQueue: #8 (IdoPgsqlConnection, ido-pgsql) items: 41, rate: 17.1833/s (1031/min 5352/5min 16240/15min); empty in 10 seconds with an incresing estimated time for the WorkQueue to empty. It never does (although the DB is working perfectly well, no problems in the database logs at all, and I can connect to both the IDO and the Icinga Web 2 database), and the situation only clears up when I restart the database. After both Icinga 2 and Icinga Web 2 reconnected to the database, everything is OK again. Cheers, Peter. > On 30.
