Re: What is this error message?
This WebDNA talk-list message is from 2006
It keeps the original formatting.
numero = 66521
interpreted = N
texte = Perhaps exclusivelock either works successfully or fails after the preset timeout period without reporting any error? I don't remember details like this any more, but it might not hurt to check the docs for exclusivelock and see how it actually behaves ... And I'm sure you have already done this, but just as a reminder to others, don't forget to confirm that the db changes you're doing inside the exclusivelock context are actually being saved.
