This forum post will help you troubleshoot issues related to Application Configuration (Clustering, Performance, System Optimizations etc.) 

Debugging Steps

1. Clustering service by default is disabled, we need to enable it from property abpm.cluster.enable to use clustering.
2. While using Clustering make sure all the nodes have the same version of Adeptia Suite installed on them.
3. While setting up a clustered environment make sure that all the nodes of the cluster use the common Backend and Log database.
4. For better performance on the Production system, follow all the recommendations on our Performance Tuning Guide.
5. Check if the System CPU and Physical memory are not completely occupied.
6. Check the Adeptia System Console for Adeptia's Performance and Usage statistics.
7. Check the log files for any possible errors. (Application Logs Location)
8. Check the LogsArchiveAndCleanup.log file for any possible errors during cleanup.
9. Restart Adeptia in case you are unable to access it or it is not processing files. https://support.adeptia.com/entries/23390371-How-can-I-restart-Adeptia-properly-
