"cannot rollback - no transaction is active" - any hints?

Hello Arnaud,
What can you see/guess from the following logs?
Would an inappropriate call to "rollback" cause the db server stop working?
Thanks.

mORMot logs:

Please, compile your project with map file. It give you a proc names instead of addresses in the exception logs. To enable map set Compiler options->symbol reference info to Reference info

Re: "cannot rollback - no transaction is active" - any hints?

I guess there is something wrong with your SQL statement executed in first line, during the Batch sequence.

Also ensure you have the latest revision of the framework: current is 1.18.3238.
We fixed some issues with Batch processes some weeks ago.

Please do NOT post huge logs in the forum.
Put the logs in a link, using GoogleDrive or PasteBin, as stated by the forum rules: http://synopse.info/forum/misc.php?action=rules

@mpv,

Thanks, will include the "symbol reference info" from now on.

@ab,

Thanks, the version I'm using is from Dec 4, 2016 (https://github.com/synopse/mORMot/commi … 1471514b3e), so I think it's ok.

Update 1:
I'll check the version of the executable in question and compare it with the mORMot version. Yes, I remember that fix - it's about "thread b" might wrongly commit transaction started by "thread a", right?

Re the log entries, to be honest, it's only 11 lines, it's far from huge, right?
