384.98 - monitors randomly wake up from sleep mode


one of our machines has the behavior that the connected monitors randomly wake up from sleep mode and then immediately go back to sleep mode.

Steps to reproduce:
turn on computer
wait until the monitors go to sleep
monitors wake up after a random time and then go back to sleep after some seconds, this happens between a couple of times per hour til once or twice a day

The machine affacted is a FUJITSU Workstation CELSIUS M730 E5-1620v2@3.7GHz, 4x4GB RAM and 2x1TB HDD with an NVIDIA NVS 510. There are 4 monitors connected to the machine.
We are running RHEL 7.4 with the kernel 3.10.0-693.11.1.el7.x86_64.
I attached the nvidia-bug-report.log.gz created a couple of seconds after the monitors woke up. The time the monitors woke up was approximately 2017-12-14 16:51:40.
