PostgreSQL Dataflow Refresh Error

Hi,

 

I am refreshing a large table in PostgreSQL and it is returing the following error. Is it simply to do with the size or something different? Any advice would be much appreciated.

 

Error: Encountered user gateway exception: '[DM_ErrorDetailNameCode_UnderlyingErrorCode]=-2147467259 [DM_ErrorDetailNameCode_UnderlyingHResult]=-2147467259 [Microsoft.Data.Mashup.ValueError.DataSourceKind]=PostgreSQL [Microsoft.Data.Mashup.ValueError.DataSourcePath]=cc-data-warehouse.postgres.database.azure.com;Master [Microsoft.Data.Mashup.ValueError.ErrorCode]=-2147467259 [Microsoft.Data.Mashup.ValueError.Message]=Exception while reading from stream [Microsoft.Data.Mashup.ValueError.Reason]=DataSource.Error [InnerType]=MashupValueException PostgreSQL: Exception while reading from stream [GatewayPipelineErrorCode]=DM_GWPipeline_Gateway_MashupDataAccessError [ErrorShortName]=GatewayClientErrorResponseException[GatewayId=741247]/MashupDataAccessValueException[ErrorCode=-2147467259 HResult=-2147467259]/Wrapped(MashupValueException)[ErrorCode=-2147467259 HResult=-2147467259] [ExceptionErrorShortName]=GatewayClientErrorResponseException[GatewayId=741247]'.

It appears to be due to the size of the table itself, so it's being reduced to see if that resolves the issue. Thanks for the feedback anyway.

This looks more like network instability?
