Precipitate in DIG Hybridization Solution?

I have noticed presence of precipitate, at the end of pre-hybridization 
and hybridization, in the hybridization solution recommended for 
DIG-labelled probes by Boehringer Mannheim. The composition of the 
solution is as follows:

1% Blocking reagent
0.1% N-lauroylsarcosine
0.02% SDS

Do other DIG users have similar observation? Can this cause failure of 

I did the hybridization at 51C inside a Hybaid roller-bottle oven. 
Heating the solution containing the precipitate in boiling water bath for 
10 min did not dissolve the precipitate.
