ElectrumX dogecoin doesn't work about electrumx

[amanusk]

Any success in getting it to work?

Using rocksdb, my sync got caught at block 3,611,692, where it crashes trying to deserialize inputs. Although prior to that it had actually been working without issue for about 3 weeks.

Switched to leveldb and still a few hours away from this mark. I don't know if it's the same issue - usually 'Killed' happens when RAM runs low or too many threads are being called. I'm still a few hours away from catching back up on the sync so we'll see if it works I suppose.

EDIT: Looks like my issue is the same as #99

[amanusk]

Can confirm that solution in #99 fixed the issue for me
