Cannot remove lock file '/tmp/.X...-lock': Operation not permitted

This warning:

205287 NXNODE   WARNING! Cannot remove lock file '/tmp/.X1030-lock': Operation not permitted

has been reported in a specific multi-node environment and indicates a possible issue in the session cleaning procedure which is not performed as it should.

This issue looks to be triggered by some race conditions and it occurred when (i) the automatic disconnection to make room for new sessions is enabled on the Enterprise Terminal Server (ii) and the node host where the old session has to be killed was heavily in use.
