I had an issue with the v10 (Case # 05348431) regarding the arithmetic overflow error. I received a patch and also the recommendation to upgrade. I upgraded and after a week, the error occurred again

I am using the default installation, with the MSSQL Express local install.
I have a backup job in the main location and a clone job to a secondary location.
I believe the error is coming from the WAN accelerator component. The job ran well but the reports are completely messed up.
Any advice ?
Thank you
Costin
