We'd need a more detailed error message, but I guess this is moot now.

Hm, too bad. Not sure what to do about this bug report now that we no
longer have the offending journal file. I'm tempted to close it and
reopen again, in case you run into it again and we can further debug this.

Old journal files are removed when you hit certain limits. The default
retention policy is size based. As long as you have a certain amount of
free space, old journal files are kept. If those limits are exceeded,
the oldest journal files are removed first.

That seems very strange. The only case where I personally ran into
journal file corruption is when I had to power cycle the machine.
But you said that journald ran uninterrupted for 40 days.
Would it be possible that this is a hardware or file system issue?
