Hello,
    We are running an app with HSQLDB 1.7.0 in production, and we see intermittent exceptions thrown when an hourly checkpoint command is run:

java.sql.SQLException: File input/output error: S1000 File input/output error: C:\LicenseManager\database\embedded.script in statement
at org.hsqldb.Trace.getError(Trace.java:226)

What does 'S1000 File input/output error' mean?

Thanks,
Matt
