Strange cachemgr output

I discovered this strange output from cachemgr today:

Protocol Object Maximum Current Minimum Hit Trans Transfer Transfered
          Count KB KB KB Rate KB/sec Count KB

   OTHER -1 0 -53 -53 0.00 0 7671 67020

   TOTAL 49886 676252 567032 542584 0.28 0 168660 1166819

Shall I be worried about minus kb being in the cache? Has squid found a black
hole on my harddisk?
