Hi Marco, I understand it is currently difficult for final users like you to figure out where one's problem lies within the OpenChange/SOGo stack and looks reasonable to take the shortest path for blaming. In the end it doesn't really matter OpenChange is not at fault here because the visible result for you is Samba dying and your AD getting down. It makes everyone nervous and we both agree that is not acceptable when running in production. This is not a dead end and that can be improved quickly. See below. > Anyway, I found a litte dangerous that in situations like that one, > samba dies, leaving the whole AD infrastracture upside-down. I agree with you. Initially the abort() cases - that causes samba to die on purpose - were restricted to a very limited set of cases and situations that "should not or could not happen". This was used as a safety guard when we reached leaves of the graph. We almost never reach these cases anymore. This model however got extended to less critical paths for development convenience but introduced the side effects you unfortunately experienced. We can fix this easily: 1. chase the abort() used in non critical paths and remove/replace them with termination or error code + add more logging. 2. Rework the logging so you can identify where the problem initially lies and helps reporting issues in a way that is relevant both for you and OpenChange/SOGo. In this case, one's feature may not be working but that won't impact the overall system and still provide a way to find the cause. > Now I am testing, before to go to production, the environment, and I did > find that is quite easy to create a problem in openchange and cause > samba to die. > For example, a few minute ago I create a new user, create an outlook > profile, all ok. then > 1) I create a new folder "Test" in web > 2) Sync outlook, Test appears as expeceted > 3) Create a Subfolder of Test, named Test1 via web > 4) Sync outlook, no test1 appears. The same closing and restarting 4) is a known issue for quite some time. OpenChange has the infrastructure to fix this bug but SOGo wasn't using it yet. This is something afaik they are working on this for next release. This being said - and from my experience - I'm doubtful on the relevance of tests mixing Outlook and web interface. I don't argue on the path to abort() that needs to be less pedantic - we agreed on this - but generally users either use Outlook or web interface, not both at the same time.
