Just had my masternode go down a few hours ago, running 1.1.4.6 built on Saturday afternoon. Restarted it with valgrind so far without issue, below is the end of the debug.log if it might be of help:
2018-08-28 06:08:07 CGovernanceManager::ProcessVote -- Old invalid vote , MN outpoint = 2bd839a7c42729200f4b9d753a68b111ae2d55ee60b89455beae332c47f6d7a3-1, governance object hash = a5f79b3e5e2b0cbb6764bcfc093aa3c68e4521e9d4e03c590319e33152249d25

2018-08-28 06:49:22 runCommand error: system(./biblepayd -erasechain) returned 32512
So it is revealing. On my end I need to take a look at something - it appears we do sort of jump the gun in the "Found chain with blocks marked invalid". We supposedly attempt to replay the last 205 blocks when that happens, but on your node it appears we jumped down and tried to restart it with -erasechain (see last line in the log) and that command returned an error (error 32512).
So on your end, if you are starting biblepay from an absolute path, (like from a script) that would explain 32512. Ill take a look at this. If you want autorecover to work, you could modify your script to : unalias cd && cd ~/biblepay/src/qt && ./biblepayd when it starts and then it should recover when this happens. But this is just for the time being as we make this fullproof and resilient.
