It's not just errors in the log file, because even the guardian has
log entries when it's starting the server. I have 301 log entries in a
33.1KB file, but most of my entries are the guardian starting the
server, which is only represents 2 lines of text. By the way, this is
my development machine and it does get rebooted quite frequently. And,
this amount of log entries was accumulated over the past 12 months.

Then this might require another thread on the server to manage this
archiving schedule.

If someone gets a log file of 200KB per day, I would start worrying.
Instead of a size cut-off, maybe a number of days cut-off! This way a
user could configure the number of days that a log entry will stay in
the log file. This way, it could be set to 7 days or even 365 days.
But, automatically archiving the log file should be an option that can
be turned off or on, and configurable to have only one archived log
file or more. And, that the archiving(if it is required) would only be
performed when an entry is written to the log file.
