NSX segment ports stuck as "in progress"

Products

• VMware NSX

Issue/Introduction

During the creation of VMs or VNICs for VMs bound to an NSX segment, the corresponding segment ports remain in state "in progress" and the deployment task does not complete.

In the logfile /var/log/proton/nsxapi.log on NSX managers, you can observe lines similar to:

2022-08-05T02:08:23.381Z  WARN intelligence-agent-delta-config-producer PolicyProducerUtils 4239 INTELLIGENCE [nsx@6876 comp="nsx-manager" level="WARNING" subcomp="manager"] Failed to retrieve all related compute members of group Group/xxxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
com.vmware.nsx.rpc.StatusRuntimeException: UNKNOWN: leaked exception: java.util.ConcurrentModificationException

Environment

VMware NSX in versions 4.0.0 or 3.2.1

Cause

The segment's creation did not complete due to an exception in the Grouping workflow, making it stall indefinitely on the failed RPC query, so the creation of ports on this segment also cannot complete.

Resolution

This issue is resolved in VMware NSX versions 3.2.1.1 and 4.0.1, available at Broadcom downloads.
If you are having difficulty finding and downloading software, please review the Download Broadcom products and software KB.

Workaround:

You can restart the Controller service on all the management nodes in order to resume the segment and port creation workflows, this can be done by running the shell command:

# /etc/init.d/nsx-ccp restart
