New MES install, been working fine for the last few days now randomly throws up this error for a few minutes at a time (3 or 4 entries per second)… Anyone seen this before?

Hi,  
When it started throwing the errors did you add any production model items or change production model item names?  
I am wondering if it is not random but caused by a previous event in the log or maybe it occurrs at a certain time?  
What versions of the gateway and modules are you using?

I’m trying to gather more information to see if we can find a place to look.

Thanks.
