Description

When running a bunch of experiments at the same time, I sometimes get the following error for a few seconds:

Unexpected server error. Please contact the developers!
Status code: 500

I am running experiments for the random forest on one big machine with 72 cores. Especially with small datasets the models are built extremely fast, so I suspect the server might be unable to handle all the requests. At the same time I am also running experiments for svm in a batch with five 4 core machines.

Research direction

Start by reproducing the concurrent random-forest and SVM experiment batches described in the report, using a large machine and multiple smaller machines. Investigate how the server handles the simultaneous requests and verify that the workload no longer produces intermittent HTTP 500 errors.
