We were in the process of upgrading from 1.2.2 to 1.2.3 in our deployment and unfortunately run into problems (Win7 32Bit). Downgraded netxms server back to 1.2.2, deployed the 1.2.3 on Win2K  server and had the same result. Looking at the debugs below, I cleared the database and re-initialised the database. Netxms would then run successfully. I have had a look at the table which it was querying and there is nothing particularly interesting, totalrow count was around 300000 and the itemid rowcount being queried was 4290. I am comfortable that the mysql instance is good as this has been live in the 1.2.2 installation and is still good subsequent to the downgrade.

Sorry I am not sure which additional information might be constructive?
