Network Interfaces randomly dropping off
We are experiencing a rather baffling problem with our network interfaces on our host system. The system has 4 motherboard NICs, 2 Intel Quad Port boards and 2 DDC fiber channel boards. We are seeing random drops of IPs on some of our NICs and have to do a network restart to get them back. This problem seems to clear up by disabling Network Manager and letting the system operate from network service. Our colleagues at our sister company are also experiencing this issue. We are using RHEL 7.4. We are looking for suggestions and solutions. I would also like to know if anyone else out in Linux land is experiencing this issue?
