Issue/Introduction

  • Segment port appears to be stuck in an 'in progress' state in policy view of the NSX Manager UI. 'Deletion in Progress' is being reported for that port like the screenshot below:

  • For the affected VM, searching the NSX UI may reveal a duplicate 'Uninitialized' segment port that shares the same VIF ID (as illustrated in the screenshot). But please note that this is not always observed:

  • When you check the 'Last Modified Time' with the vMotion history of the VM, you might see a correlation between the modified time on the port and the time of a vMotion task against that VM.
  • You may see connectivity issues with the VM connected to the segment port, if allow DFW rules are configured using segment port tagging. In such a scenario in the Manager UI while in Manager view you might observe that the port is 'Up', but the tags are missing which leads to packets being dropped.
  • At times it is observed that the NSX Manager cluster intermittently goes into a degraded state.

Environment

VMware NSX 4.2.x

Cause

  • The issue may stem from NSX Manager cluster instability, specifically the Management Plane is down or unstable.
  • Suspected that port deletion/creation requests are being missed when the MP connection between the Host and the Manager is unstable.

Resolution

There is known issue with below NSX version where the NSX Manager is Impacted by JDK-8330017: ForkJoinPool Stops Executing Tasks Due to ctl Field Release Count (RC) Overflow due to which the MP/CCP connection between the NSX Manager and the ESXi/Edge Transport Node is not stable.
VMware NSX 4.2.0.x
VMware NSX 4.2.1.0, 4.2.1.1, 4.2.1.2, 4.2.1.3
VMware NSX 9.0.0.0

For resolution, see NSX is impacted by JDK-8330017: ForkJoinPool stops executing tasks due to ctl field Release Count (RC) overflow.

To workaround this issue, do a rolling reboot of the NSX managers, as per the KB NSX is impacted by JDK-8330017: ForkJoinPool stops executing tasks due to ctl field Release Count (RC) overflow

Additional Information

Kindly also refer to the KB Segment port appears to be stuck in an 'In Progress' status in the NSX Manager UI due to 'Deletion in Progress' if rolling reboot of the NSX Manager doesn't fix the issue.
