I usually don't have many corrected blocks(Only a few every week such as 14 or so) but then every once and awhile I get a couple seconds with just a burst of a corrected blocks. It's not really an issue at all but just curious what can cause this? Maintenance? A little something in the lines that happened that one second?
As you can see from the error table I haven't had one corrected block since 3 days ago. 3 days ago was a quick 30k corrected block burst.
