Issue/Introduction

• The following alarm is displayed on NSX UI.
  • Application on NSX node <EDGE> has crashed. The number of core files found is <X>. Collect the Support Bundle including core dump files and contact VMware Support team.

• An L4 VIP was deleted or its IP and port were modified. An L7 VIP was created (with a transport rule) using the same IP and port as the L4 VIP.
• Traffic traversing the load balancer is impacted.
• An nginx core dump is present on edge in /var/log/core
  • e.g. /var/log/core/core.nginx.gz

Environment

NSX-T Data Center 3.2.x

VMware NSX 4.x

Cause

An L7 VIP is created using a previously used L4 VIP's IP and port. The L4 session remains and is remapped internally which causes nginx to crash.

Resolution

Issue is resolved in 3.2.4 & 4.1.2

 

Workaround: As the L4 VIP is already deleted/modified, putting the Edge (active & standby) in/out of maintenance will clear the session and prevent nginx from crashing.
