Subject Master build queue
Date Thu, 10 Dec 2009 08:48:56 GMT
I hope no one minds too much... I just increased the number of slots in the Hudson master from
2 to 3. What happened is that I've got two jobs which are both set as 'multi-configuration'
jobs. Each job actually spawns a child job in order to do the work, but both the parent and
the child are in the executor queue at the same time. The parent does no work, but ties up
a slot.

So my two jobs will sometimes get triggered at the same time. Then both parents sit in the
queue and neither can spawn a child to progress any further. Adding one more slot solved this...
until a third multi-config job happens to hit the queue at exactly the same time.

Ideally, I'll look at ways to avoid my job having to be tied to one node.
