OSError: [Errno 105] No buffer space available

Not sure how to approach this or if it is something we can even handle in wepy itself.

Seems like not a wepy issue. Is this link relevant? https://blog.mphomphego.co.za/blog/2017/06/28/why-am-i-getting-errno105-no-buffer-space-available-when-subscribing-to-multicast-addresses.html

Yep I was too hasty in this issue. Wanted to make sure I didn't forget about it :) I ended up looking at the log and it was just an out of memory error...
