Cannot ssh into Fuse using client script or ssh utility.

Issue

• ssh into fuse hangs with following message

[root@UFFXPRDTELI01 ~]ssh -p 8101 -o PasswordAuthentication=yes -o PubkeyAuthentication=no -vvvvv admin@localhost

• It just hangs here. I do not want to restart the service as this is a production environment. How can I restart just the ssh/shell bundle?
• It seems like there are few connections in the CLOSE_WAIT state open on port 8101:
