Hi Chris, You haven't let us know what sort of errors you are seeing... but, it does (at a glance) sound like you are running a *lot* under very little resources. It sounds like you are running DSpace + Wordpress (and all their pre-requisites) with just 4GB of memory total? That's impressive, as I'd expect either DSpace alone would want at least 4GB of memory (and Wordpress may require something similar).
Overall, if you want to run everything DSpace requires on one server, I think you'd need 4GB at a minimum *just for DSpace*. Inspired by your question, I went ahead and wrote up some "bare minimum requirements" based on what works for me on a memory-controlled Docker setup of DSpace 7. https://wiki.lyrasis.org/display/DSDOC7x/Performance+Tuning+DSpace#PerformanceTuningDSpace-BareMinimumRequirements I believe these requirements to be accurate, but it's possible we'll need to tweak them based on what others report in production scenarios. In any case, I do think you will need to think about either adding RAM, or alternatively finding a separate server for either the frontend or backend (as you do not need to run both on the same server). You also may need to look closely at Wordpress & MysSQL memory requirements, as they could also have an impact on your memory usage & therefore DSpace's performance.
