Log message "Nicmgmtd could not accept connections. Error is : Interrupted system call" during ESXi reboot

Products

• VMware vSphere ESXi

Issue/Introduction

When rebooting a VMware ESXi 8.x host or performing maintenance/updates that trigger a service restart, observes the following error messages in /var/run/log/syslog:

YYYY-MM-DDT09:25:50.510Z In(14) nicmgmtd[PID]: Got signal : 15. Shutting down daemon.
YYYY-MM-DDT09:25:50.510Z Er(11) nicmgmtd[PID]: Nicmgmtd could not accept connections. Error is : Interrupted system call

Environment

VMware vSphere ESXi 8.0.x

Cause

This message occurs during the standard shutdown sequence of the ESXi host.
The nicmgmtd daemon receives a SIGTERM (Signal 15), which is the standard signal used by the operating system to request a graceful termination of a process.

Resolution

These messages are a normal part of the daemon's shutdown process and do not indicate a functional failure of the NIC management service or the network drivers.

If the messages only appear during a host reboot or an intentional service restart, they can be safely ignored.
