Hi Michael, Can you do the following? Turn on Zope event logging by using the STUPID_LOG_FILE environment variable (this is documented in LOGGING.txt inside the doc directory, I believe). Log the events to a file named "debug.log". Set another environment variable: CST_DEBUG=1 Then restart Zope. One way to do this in one fell swoop is to do: ./start STUPID_LOG_FILE=debug.log CST_DEBUG=1 Check the debug.log file to make sure things are getting in to it. You'll see Zope startup messages, likely. Then cause the error to occur by calling your external method and send me the log file in email along with any other details you might be able to provide. Many thanks! - C michael kobald wrote:

This application may be in an invalid state and must be restarted before database updates can be allowed. Beware though that if the error was due to a serious system problem, such as a disk full condition, then the application may not come up until you deal with the system problem. See your application log for information on the error that lead to this problem.
