There is a label named ChangeStatus: in Panorama’s EnterpriseServerLib library. This message must mean that that the in memory copy of the library has been damaged, or maybe just closed? Restarting would load a fresh copy of the library. Do you have web procedure code that is closing databases or windows? If so, be very careful that you are closing what you think you are. Since everything is invisible it would be easy to close the wrong thing without realizing it. Unfortunately your web publishing procedures essentially run as root as far as Panorama’s internal code goes, your web publishing code has the same privileges as code that I write that goes into the server, so you can break things. (Note that this has nothing to do with operating system root level privileges, this is just within Panorama.)
