SQLITE_E_IOERR_MMAP

SQLITE_E_IOERR_MMAP corresponds to SQLITE_IOERR_MMAP. SQLite received an I/O error in the VFS xFetch or xUnfetch operation while mapping or unmapping part of a database file.

What to check

Check process address-space pressure and the availability of the file while it is mapped.
Check storage and filesystem events; an unavailable or replaced file can make mapped I/O fail.
Record whether the application or VFS explicitly enables memory-mapped I/O.
