Occasionally I get this error message when running an application in the IDE:

Project MyProgram.exe raised exception class EEDBError with message 'ElevateDB Error #601 An error occurred with the statement at line 45 and column 15 (The table MyData is corrupt (Error flushing header to disk))'.

But when I verify or repair the table no problems are found. Just to be sure I have repaired the whole database but still no problems discovered.

Anyone else experience this or am I just the lucky one?

Oops, forgot to mention this is with 2.26 Build 2.

It last surface around 2007 / 2008 - I was one of the unwilling participants


I'd say put together a test project that reliably replicates the error and send it off to Tim. If you can't then notify him with as much detail as possible.

This means that EDB had an issue writing the table header data to disk.  Are you performing any threading in your application at all ?  If not, then my next guess would be antivirus/security software interfering with the writes in some way.  EDB writes the header to disk twice: one time with a "writing" flag set, and then again with it cleared, followed by a flush to disk if a transaction commit or if the TEDBSession.ForceBufferFlush property is set to True:

If this is reproducible, please send me what you've got along with instructions on how to reproduce, and I'll take a look.

Thanks Tim and Roy,

It happened a few times over a couple of days and hasn't happened since.  If it happens again and I can work out a way to reproduce it I will create a project.
