The problem: You have a web agent somewhere which uses LotusScript MessageBox to output an error message. However, the message doesn’t say which agent or database it’s being output by, so you need to locate the agent which is printing the text.
The solution: At the console,
set config AgentThreadDebug=1 tell http restart
The HTTP task will then display a debug message for each web-triggered agent that starts or ends.
Obviously, you’ll want to turn this off when you’re done debugging.
