I'm unsure, but it could be due to the limited Linux distro running on
the device, perhaps? If I used pipe it gave me errors about
wrapper.port being undefined in the log.

That is likely the issue. The device only has 512MB ram + 512MB swap,
so I set max memory use to 192MB as a conservative estimate. I'll
tinker around a bit with more ram, but I'm aware the device is low on
RAM for running something like Freenet. It was/is a testbed for now.

No downloads, although it sees quite decent throughput just from what
other nodes send/receive through it having sent and received about 6GB
data total over the last 15 hours.
