Hosted API Breaks Shortly After Being Uploaded

When using the Hosted API Service, we can upload our service jar and make requests successfully, however, shortly afterwards all requests start failing with random weborb exceptions, such as:

com.backendless.exceptions.BackendlessException: weborb.reader.NullType cannot be cast to weborb.reader.NamedObjectServiceException

and getting a ServiceException when trying to fetch a BackendlessUser with a simple where clause like “facebookId=‘111111111111’”

Deleting and re-uploading fixes our problem, but only temporarily… only takes about 5 minutes or so for the problems to start happening again.

AppId: E2FCAB80-B95E-E671-FFF9-A587FA266900

If you could create an isolated sample demonstrating the problem, it would help us track it down.

How exactly would I create an isolated sample for this? Its a set of web services that all error in some way and they touch multiple tables in our database. I could email you the service jar.

Service jar will work too along with instructions what methods to call with what argument values (if it matters for reproducing the problem). If the code is dependent on your schema, we would need an export of it as well, since we will not be deploying it to your app.
