It is definitely the case, that is what I am looking at, it is due to the fact that the Agilo config needs to keep stored some properties that are used by others, and these properties are read only. The problem is that the event of saving the config from whatever Admin page, triggers the reload of it, and this is sometime done outside of Agilo control, whatever other plugin can write the config file. So what we could try to do is to put a lock on the load, and block all the thread till the reload is completed, hopefully this will solve the problem. The problem here is that it is not easy to reproduce :-( > My users are getting grumpy that they keep seeing this, and I can't > seem to figure out the cause. We are getting grumpy too ;-) I can try to solve it with the lock and send you a patch so you can try this out ok for you? It would help if it is happening so often on your side, to understand which conditions are triggering this... do many people save or change things in the Admin site? How many concurrent users you have... whatever you can figure out would help...
