That would be a completely unworkable solution. I'd say there's no chance of a "fix" since the kqueue design is what it is. Ganglia is violating the (poorly documented) requirements of the interface. To make a FreeBSD port work, we'd be forced to maintain a separate APR package just for ganglia since kqueue is the highest performance way to implement this functionality. We'd either have to install it with non-standard names or face conflicts with the primary version. If precommitting to everything before daemonizing the process is this critical, the code needs to be refactored to open the sockets, but not set up the pollsets until after the fork. If that's done, everything should be just fine since there's basically no chance the pollset creation will fail unless you had no memory available. -- Brooks
