TREX 7.0 TREXISAPIEXT.dll high availability problem.

Question

EP6.0.11/14
TREX7.0
Trying to configure EP with a Distributed TREX. Got 2 TREX 7.0 servers each with http (application pool).  If I have both application pools up, trex monitor in EP will drop indexserver and queueserver and indexing/searching is not possible. However, if only one of the application pool is up TREX monitors shows healthy queueserver and indexserver.
TREX administrator doesn't have any issues though.
Any help would be appreciated.
