Linux sloppy mount

Could anyone describe to me what sloppy mount is? There's two mount points on my server but I have no idea how to erase the sloppy one. I hope some one could explain to me the potential faults or what's happening under the hood. Appreciate your help:)

ILTLVLSSC418:/etc # mount
nfsserver:/export/sapmnt/T10 on /sapmnt/T10 type nfs (rw,soft,retrans=2,addr=10.96.88.7)
nfsserver:/export/saptrans/trans1 on /usr/sap/trans type nfs (rw,soft,retrans=2,addr=10.96.88.7)
nfsserver:/export/sapmnt/T10 on /sapmnt/T10 type nfs(rw,nfsvers=3,soft,retrans=2,sloppy,addr=10.96.88.7)
nfsserver:/export/saptrans/trans1 on /usr/sap/trans type nfs4 (rw,soft,retrans=2,sloppy,addr=10.96.88.7,clientaddr=10.26.91.11)

The "mount" command result is shown above.

Plus I could not execute "umount", as it would fail and remount back.
