In all of the above errors there is a network problem. These errors are all regarding a loss in communication between different Pervasive engines.
Although the network can be active, these errors occur in that instance where the communication is dropped between Pervasive engines. It could be like a spike in communication, after the error occurred the communication is already restored again.
Please get your IT technician to have a look at your network and test the communication.
You can also view the PVSW.LOG file which will have a recording of the occurrence of these errors.
