White or yellowish-white gunk at solder joints indicate to me that there is a pinhole leak in the solder joint. I also see that often in cheap brass castings made in China. The blue-green on the pipe can mean flux wasn't cleaned off and the residual acid corroded the copper for a while. However, on a valve and it's at or just below the gland nut it can mean the gland packing has failed and the valve is leaking at the stem or the gland nut is loose.
