Comment 152 for bug 237970

What does that error message mean: "Unable to quarantine <filename>"? Is there some kind of virus scanner or other "security" software preventing files from being written?

From the log, it appears that the "unix-dotlock" VFS is being used. With that
VFS in use, SQLite uses "dot-file" locking, which should work over SMB, NFS, or any other filesystem where file locking is known to be broken. So it is unclear what the problem is. Certainly, nothing in that part of SQLite has changed in a long time. Which SQLite upgrade broke the build?
