Environment

VMware NSX-T Data Center
VMware NSX-T Data Center 2.x

Cause

Issue occurs only if storage vMotion was performed on the host before doing an in-place upgrade from NSX-T 2.3.x to 2.4 and hosts running ESXi-6.5P03 (build 10884925). The switch security module from NSX-T 2.3 does not get removed if storage vMotion was performed just before the host upgrade. The storage vMotion triggers a memory leak causing the switch security module unload to fail.

Resolution

Currently there is no resolution.

Workaround:

Perform maintenance mode upgrade.
Put the host in maintenance mode, reboot the host, followed by NSX host component upgrade..
