Looking in my bitcoin.conf I see I have a line "prune=550" will this cause problems?
I don't think the pruning is tanking your node, but it won't work with Armory anyways.
Ooof, yeah. Armory needs a full ~145GB node, not a pruned one
Will you have enough space available for this once you turn off pruning?
As for why core is failing... not sure. I'd have thought if Armory was starting core itself too (there is a setting for this by default), then you'd be able to find bitcoin process it spawns.
Hate to fall back to this, but restart system?
To answer another question:
Where it says "Memory Pool" and "current number of transactions," that number is not staying put, it's growing -- will i need to wait for it to finish before it will work?
This is the current amount of transactions that are pending and waiting to be mined into a block. Not something to worry about as a user, except for figuring out transaction fees
