Everything had been working fine then it stopped syncing it would not go past 838,324 to catch up to full syncing.
I have the latest Chia version and it hasn’t moved for several hours likely longer before I realise.
Below is what I have found in my debug.log which I think is the most relevant.
full_node chia.full_node.full_node: ERROR sync from fork point failed err: database disk image is malformed
