Hard to trace this bug and it will probably take loads of time to find it, it might be not related directly to your code and could be introduced in coin you forked from. I'm not part of the community, my participation was limited to find probable cause and ensure it wasn't intentional(it wasn't).
Dude, do your due diligence and research a topic before you spout off about it. Someone already pasted the code, not that you would understand what you are seeing.
It piece of code from Skype chat between me and C-CEX, it was removed from bitcoin long ago, but remain present in litecoin forks and litecoin itself. Didn't jump into conclusions yet, but found some evidence it could cause behavior with the key pool:
https://github.com/bitcoin/bitcoin/pull/2904 . In that case allmost all litecoin forks are affected, just blowed up on SSD.
