Syslog Server 9.6.7.1 Win 2016 - 'System.OutOfMemoryException' was thrown.

Installed Kiwi Syslog Server 9.6.7.1 on  Win 2016 yesterday and have started to dive into the setup and configuration. Currently running the 14 days trial version while waiting for the license. Managed without to much issues to receive syslog events from our web proxy and firewall, create filters, configure display and all that. Also realized that we should maybe not have both the proxy and firewall send to same port, should use different ports. But, the real issue is that we did notice that for some reason the server stopped receiving events - and we could not figure out why. Until I by accident came to press CTRL + R and opened the error.log-file

and in the SolarWinds.SyslogServer.Engine.log I see

Have not found any ini/config file where it seems likely to change settings related to this. Anyone has suggestions/hints?

I have seen a 'System.OutOfMemoryException' error message when KSS received a large amount of Syslogs and ran out of memory.
