That error message can happen for the file content being corrupted. One
form of corruption can be truncated because of running out of file
system space. But there can be many others. Failed writes or later
read-back problems are possibilities. Bad RAM content that was written
out could be involved.

Did you check the console output/log for any messages that might have
been from the time frame(s) for the file generation or read-back?

There are a rather wide range of possibilities. If it turns out to not
be readily reproducible, then the details may never be known.
