Almost surely, some part of your application creates cyclic objects.

Cyclic objects are dangerous, as they often cannot be garbage collected.

While acquisition wrappers appear in high number, they alone
are innocent. The high number just indicates that acquition wrappes
are somewhat referenced by the cycles (and may be part of them).

Look further down the list whether you find prominent (usually rare)
objects in high number. Such types can give you a clue towards
the problem's cause.
