Hi Chaps, I'm getting the aforementioned warning in my logs from a closed source piece of software. The software helps us convert over some old proprietary data files, and it's basically just done a COPY into a newly created table, after the warning it then goes on to create some indexes. I presume it's issuing some sort of commit or rollback without a begin, however the programs authors are telling me that's not the case and their software is not at fault. Does anyone know if something else could be causing it? I've posted a detailed log here: http://privatepaste.com/cb0iywATbd .. if someone would be so kind to have a quick look I'd appreciate it. I've posted everything, so it's about 1000 lines. The warnings are on lines 459 and 475. I've tried to follow the StartTransaction / Endtransaction lines and I don't think I can see an error there. Is there a possibility its something in PortalRunUtility ? Thanks Glyn
