We are experience some performance issues, in the Oneclick console that is integrated with CAPC.

1 - Loading times to show the landscapes

2 - Loading times to show alarms

3 - Unresponsive console in general

4 - Showing a list of "unknown" models in the locater tab

Restarting Tomcat only solves some problems in the moment, but they persist.

I'm constantly seeing this error in stdout.log: (for all users)

By looking at the following article:


I've proceed to increase the RAM in Oneclick and also change the ModelRepository.ThrottledModelReadCount parameter.

Oneclick client configuration is set to 1500 Mb.

The Spectrum installation is in windows 2019 servers, Oneclick, MLS and a second SpectroServer.
