David Lloyd updated JBAS-9149:
------------------------------

    Fix Version/s: Open To Community


The overwhelmingly most likely cause of this problem is the Log Window of Death between the time the bootstrap log handlers are shut down and the "real" log handlers are started.  This is a problem that has actually existed since at *least* AS 5.  The only solution is to eliminate bootstrap logging as it is impossible to atomically swap the entire logging configuration.  This is something I definitely want to do, especially for domain mode, but it is non-trivial.  For now I will assign this to "Open to Community", until and unless I have a chance to do this myself.  If you are an ambitious community member and are interested in taking this on, contact me in IRC (dmlloyd on irc.freenode.net) and we'll chat about what needs to be done.

The reason we're seeing it more often now is most likely that with our concurrent server startup, it is far, far more likely for services to be started during this window.  The logging reconfiguration process is actually very similar to AS 6 - but on AS 6 things tended to start serially so it was unlikely to be observable.

> Darran Lofthouse also reported that in some cases log messages from the start() method of one of his services would not appear, but the service would indeed be started, implying that the message is disappearing somehow.
