Master build queue
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.

No problem. The way it was though, the Cayenne jobs were going to block up the queue regularly. I have since discovered the "lock" feature in Hudson and am using that to prevent two jobs getting stuck against each other.
Still, please don't reduce it to one slot, or else the multi-configuration jobs will be unable to run ever.
Thanks

please leave slot administration to Hudson admins. we're trying to
remove slots, not add them, on the Master.
