Memory leaks and network throttling after 4 days #858
Description
Current openbazaar-go takes a huge amount of memory (almost 2 GB) once left running for just 3 or 4 days. Furthermore, once that happens, all other network connections get throttled down to 40-50 kB/s.
I'm not sure whether the network throttling is due simply to lack of memory (openbazaar-go eating all RAM and swap) or some other resource exhaustion (actual bandwidth being used by openbazaar-go). I am investigating that and I'll report here. The strange part though, is that this happened consistently on two different machines, running Debian 9 and Ubuntu 16.04 respectively. On both I experienced exactly the same throttling to 40-50 kB/s.
openbazaar-go is running with a non-root user, and even root processes get throttled.
I've been experiencing this since version v0.10, throughout v0.10.1 and now with v0.11.
