I installed upsource and am using a nginx as a reverse proxy. I gave the vm 2 CPUs and 8 GB of ram. Unfortunately some user expierence a lot of HTTP-500/502-Errors which I hope are going away with higher proxy read/connect timeouts. Is there any other parameter which can be tweaked there? Also we are getting a lot of svn-requests from upsource which are mostly propfinds, which does not seem to be related to a checkout of the repository.
