Bitcoin's error (debug file)
This is the critical error:

2018-01-07 10:22:45 ERROR: ReadBlockFromDisk: Deserialize or I/O error - CAutoFile::read: fread failed at CBlockDiskPos(nFile=693, nPos=38137925)
2018-01-07 10:22:57 *** Failed to read block


I would 1st check if you have run out of disk space?
