[ccnet-user] Queue status and current build

[Edwin]

I have a problem about queus status.when one of my project started
build in the same queue,the other projects status become pending.it
confused us which one will start build next.
not all of them need to start build when first one build finish.I just
want to make them start build one project build per time to avoid
sever crash by system.outofmemory exception.
can I tell which pending project will start build next?
thanks for help.
