Describe the issue

Btcpd crashing with:

btcpd: main.cpp:2631: bool ConnectTip(CValidationState&, CBlockIndex, CBlock): Assertion `pcoinsTip->GetAnchorAt(pcoinsTip->GetBestAnchor(), oldTree, chainActive.Height() >= Params().GetConsensus().zResetHeight)' failed.

Can you reliably reproduce the issue?

Sometimes is ok for 2-3 days, sometimes it is crashing at startup

@alexcos20 is this node fully synced, is it a new install or one that had been running for some time?

alexcos20 commented 5 years ago

Hello, It is a new install (2 weeks ago). While syncinc (took 2 days), everything was fine.

0x6b656e commented 5 years ago

Are you still experiencing this issue?

alexcos20 commented 5 years ago

Yes, found it today crashed again :(

PS: Should I checkout the git and recompile again? Could help?

Thanks,
