Quickfinder index seems not to finish for one user

Hi Forum,


I have one account which gets indexed completely by quickfinder every run.
From the POA logfile:
B241 Updating QuickFinder index: userrgr.db (2587602)

For all other users the number in the parenthesis is very low, often zero.
QF always takes several hours until it finishes because of the problem user.
What could be the problem with that user?
