Hi, I am not sure if this is the same issue as we had recently, but it looks a bit like it -- we also had a Luminous mon crashing right after syncing was done.
Turns out that the current release has a bug which causes the mon to crash if it cannot find a mgr daemon. This should be fixed in the upcoming release. In our case we "solved" it by moving the active mgr to the mon's host. (I am not sure how to activate a specific mgr, but it appears that the mgrs get activated in FIFO order -- so just keep killing and re-starting the active one until a mgr on the mon's host is active). Hope this helps!
