precipitate in NEB T4 Ligase buffer?

Just a quickie:

Does anyone know what the white precipitate is that sometimes forms in NEB
T4 Ligase buffer?

It seems to redisolve after heating to 37 C and vigorous shaking, but I am
wondering whether repeated heatings may degrade the ATP or anything else
in the reaction buffer.
