ESXi Host PSOD caused by NSX nsxt-vsip module TAILQ_EMPTY assertion failure

Products

• VMware NSX

Issue/Introduction

• An ESXi host experiences a Purple Screen of Death (PSOD), resulting in the disconnection of hosted virtual machines.
• A review of the vmkernel core dump backtrace indicates a panic triggered by the NSX module nsxt-vsip with a specific assertion failure: assert "TAILQ_EMPTY(&kif->state_list)" failed.
• Log snippet from the core dump:

VMware ESXi 8.0.3 [Releasebuild-24859861 x86_64]
2026-03-04T13:03:31.674Z cpu44:2098238)line 2147        assert "TAILQ_EMPTY(&kif->state_list)" failed
Module(s) involved in panic: [nsxt-vsip-24954728 Version 1.0.0-0 RELEASEbuild-24954728]

Environment

VMware NSX 4.x

Cause

The PSOD is caused by a known defect in the NSX component nsxt-vsip where a state list queue fails an empty check.

Resolution

Upgrade the NSX environment to version 4.2.3.2 or higher. Broadcom Engineering has integrated the code correction for the nsxt-vsip module assertion failure into NSX version 4.2.3.2 and higher
