X Forwarding broke

X Forwarding has quit working on only 2 of our AIX Servers.

Have verified our sshd_config matches on all our servers.

NAME
atmloop - get/set loopback mode of ATM interfaces SYNOPSIS
atmloop -s [-l level] [-r level] [itf] atmloop [itf] atmloop -q [itf] atmloop -V DESCRIPTION
atmloop sets or shows the current loopback settings of an ATM interface, and allows to query the loopback modes supported by the interface. Some ATM cards can be configured to echo data back to the driver (local loopback) or to the network (remote loopback). The echoing may be done at several different levels: aal AAL PDUs atm ATM cells digital bits sent to or received from the line interface analog the analog signal The levels supported by an interface can be queried with the -q option. If invoked without options, atmloop displays the current loopback settings. OPTIONS
-s set loopback mode. Followed by either -l or -r, both options to set local and remote loopback at the same time (if supported by the driver), or none of them to turn off any loopback. -l level enable local loopback. -r level enable remote loopback. -q level query loopback levels supported by the interface. -V print version number of atmloop on standard output and exit.
