To make it easier for administrators to troubleshoot issues it could be useful to keep older logfiles as well.
This one is difficult since there is no obvious right amount of logging. We probably don't want to fill up the disk by keeping every log. So how many logs are enough? Some possible options: * Raise the count a bit to hopefully cover everything people need * Have a setting and let the admin decide (they would need to push out configuration for this though) * Start limiting things on size rather than count. Perhaps put everything in a single file as well? * Delegate the issue to the system, e.g. stderr, journald or Windows system log.
Note that since bug 7640 we do have multiple files for concurrent connections. Not the same problem as here, but slightly related.
