Troubleshooting: Memory usage always at 90% or above? It's probably this SEQ setting.

Important Note: more details are available in the AWEIS Setup Guide. See the section named 'Setting up Logging...'

By default, SEQ will use as much memory as possible (90%) to cache log messages.  This is fine, if it's on a standalone server.

If SEQ is installed on a shared server (e.g. on the same machine / VM as the Interop Service, or RabbitMQ) then it is important to limit the amount of memory SEQ will use.  

to change this, open the config file located at %programdata%\seq\seq.json and change the SystemRamTarget to something lower, e.g. 0.2 meaning 20%:

The tradeoff is that when older messages are flushed out of memory and the disk has to be accessed searching for older messages becomes quite slow.
