And journalctl should still try to read the old ones but skips the corrupt entries. If that works you could schedule a restart of the journal periodically as a goofy hack work around until it gets fixed. Clearly Red Hat knows about this problem. -- Chris Murphy

I had to actually remove the journal file to get it functional again. So far, turning off the compression appears to have worked (but I'll have to watch it for a day or two to really see). -- Chris Adams <linux at cmadams.net>
