This SiteManager has a system log file which is kept in RAM and which can only contain 500 KByte.
If the log exceeds this limit, it is truncated by removing the oldest messages in the log. The log is also cleared on each reboot.
Note: If you want the system to automatically forward a copy of the new messages (i.e. not previously forwarded) in a log before it is truncated, you can use Log > Setup to schedule forwarding when full.
