Hi Nirav, which version of ThingWorx are you running and on which OS? Please also check for the access rights for the drive on which the data store is located
Thingworx 7.2.2 hosted with PTC. It's coming only when application received 12-15 simultaneous REST calls. Basically, we are inserting into database and some of the entries are not being inserted due to this error. It didn't happen with earlier version of Thingworx 7.1.3 Neo. It's coming randomly so I doubt that access rights is an issue or not.
Nirav, when you say certain entries do not get added, they are called though the same user context, correct? Do you have a count of how many entries you're trying to add and how many fails? Does the user have Visibility permissions to the Persistence Provider Thing?
