Broken pipe

Good morning Scrapers,

We've had SS Pro running on Linux for month now with hardly anything in the error logs but since a couple of days the logs are jammed with error messegaes like:

The error was Connection is broken: SQL was: DELETE FROM scriptinstance WHERE scrapingsessionid = -1 AND scrapeablefileid = -1 AND extractorpatternid = -1 AND httpsessionid = -1
An error occurred while executing the SQL statement. The error was Connection is broken: Broken pipe.

I would appreciate a hand in interpreting these. The only thing I can recall that could have caused this is a server reboot that occurred at about the same time as these errors started to show.
