Omnis Data File issues

 The issue that we are experiencing is that when users with runtimes connect to the database, they are occasionally presented with the following errors:
        •Bad file number passed to data manager.
        •An error occurred locating a header record for a slot.
        •Communication error on connection 
        The interesting thing is that if I connect using the Studio SDK, the errors don’t occur. However, if I serialize that SDK as a runtime, the errors return.
        The ODB is on an M1 Mac; which made me wonder if there might be compatibility issues.  But the same errors occur when it is shared from an Intel Mac. Almost all of the Macs are running Big Sur.
        I have tried rebuilding the datafile, however it did not resolve the issue.
    Just a shot in the dark : did you test whether record locking still works at all in this configuration, if not - then these errors would be the consequence ...
Sorry, and ODBLogLevel at 3 does not give you further informations ?
