Hi, it happens again, this time on Ignition 7.8.5 without any previous update. I’m not sure when the errors started again, but this time a gateway restart does not help. The internal db has a size of about 65.000 kb. On the same gateway, there’s a problem with system memory comsumption ([in this thread](http://forum.inductiveautomation.com/t/out-of-memory-gateway-on-windows/14808/5)), maybe this problem is somehow related. ```auto INFO | jvm 1 | 2017/07/27 15:21:15 | ERROR [SingleConnectionDatasource] [15:21:15,769]: The following stack successfully received a connection.
