If your insert is lethal or at least giving the cell problems then
rearrangements/deletions will be the result. Inducing lac for blue/white
selction will accelerate the problem. 

What was your insert orientation (i.e. direction of any ORF's in the
insert) to the lac promoter? I will hazard a guess that it was in the
same orientation and the deletion is between or even including the lac
promoter and the start of the insert.
