Hi all, We are testing DSpace 8.1 and have a set up where we use Apache server as a proxy. We have noticed that when accessing URLs to items, cols, comms by their handle OR when resolving DOIs into items we get errors from Apache (500 or sometime 504s).
A few months ago we performed changes to our Apache configs to start using the MPM event module to improve performance instead of the default Prefork. Our production DSpace 7.6.1 instance does not present these issues when using the event module, but the DSpace 8.1 server does. We can confirm that switching back to using prefork resolves the issue. Errors we see in apache are not very useful (below) and there are no errors at the DSpace end (frontend and backend).
