Database Errors

 

I am creating offline charts.

When I open an offline chart, I recieve an error "xxx Database Errrors", in the log file. The offline chart displays correctly, except there are missing bars in the chart, randomly. No pattern to the missing bars. I have accounted for all errors from no history .. and still it generates the "Database Errors" message.

All data used to create each bar is derived from the MT4 Timeseries values(Iopen,Iclose etc.) and I have checked the input data and the output to ensure that no bar created has a value of zero or less, and the time on each bar is correct. All the data in the MT4 history files is there correctly too.

Could someone please explain what a "Database Error" consists of in MT4? What can create this error? Where do I start searching? Any help is appreciated.
