Safe to delete xcsd.output.log?

I occasionally run out of hard drive space on my servers, depending on how many Xcode bots are being used at a time by the development team.

Using GrandPerspective, I see an enormous file that I'd like to get rid of. xcsd.output.log dwarfs all other files in the system, at 67.4GB.

It's a log file, so presumably I can just throw it away and it will regenerate fresh. However, keeping *some* history would be nice.

Is there a strategy for keeping this file under control, rather than letting it just grow infinitely? Or do I just have to remember to clean it out manually from time to time?
