We are connecting the blob storage to the Source on premise systems using a DMG (Data Management Gateway). We are connecting to four sources in the same pipeline. While it connects fine to some if fails for the other (this is totally random) with the following error: Mashup operation failed at Source side. Error message from Mashup execution : Integration Runtime (Self-hosted) Node Name=DMGUAT-03,ErrorCode=FailedMashupOperation,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message='Type=Microsoft.Data.Mashup.InternalMashupException,Message=We're sorry, an error occurred during evaluation.,Source=Microsoft.Data.Mashup,''Type=Microsoft.Mashup.Evaluator.Interface.ErrorException,Message=Access to the path 'MashupSessionCacheMutex_C:_USERS_DIAHOSTSERVICE_APPDATA_LOCAL_TEMP_MICROSOFT_MASHUPPROVIDER_CACHE' is denied.,Source=,',Source=,'.
Tried emptying the cache on the server where the DMG is installed but that did not help.
Can someone please explain the cause and solution to this problem?
