[Anthill] Projects stuck in the build queue

[Eric Minick]

I've heard of builds getting stuck in the build, but don't remember it 
as something that happened as regularly as you describe. Most of the 
time that the build hangs, it is waiting on something from CVS that 
never comes back, or the SCM product requests more input.

To track down this problem, it might make sense for you to change you 
logging to debug. It looks like the revision log parsing is fairly 
verbose in log mode and we might be able to get a better feel for what's 
going on with that output.

Regards,

Eric
