I95-33989 Terminating a "validate" command with CTRL-c returns to the PCLI prompt but does not stop the in-progress validation. This prevents subsequent validation attempts until the in-progress validation completes in the background.
Symptom: The following can be seen in the PCLI output:
% Error: Candidate configuration is invalid:
1. A request of type validate is already in progress. The first request was started 13 seconds ago.
Until the system is upgraded to 4.5.1, this issue will resolve itself after the background tasks have completed.

Symptom: The following message can be seen in the journal:
"state.highstate" is running as PID 29159 and was started at 2020, Jul 09 14:26:54.384868 with jid 20200709142654384868

Until the system is upgraded to 4.5.1, this issue can be mitigated by restarting the salt-minion service by executing
systemctl restart salt-minionin the Linux shell. If not manually restarted, the salt-minion watchdog will also restart the salt-minion after one hour.
I95-36416 Navigating to the DNS Config page under a router in GUI edit configuration results in error.
Until the system is upgraded to 4.5.1, this issue can be mitigated by configuring dns-config via the PCLI.
- I95-36536 Deleting a session-capture filter within the PCLI can cause the highway process to fault.
- I95-36537 Dynamic session-captures are now created with a default session count of 100 instead of unlimited.

I95-36574 After an HA interface fail over, a session collision can occur between the recovered flow and an existing reverse flow. The recovered flow does not get set up properly and can cause the highway process to fault upon session expiry.
Conditions: Symmetrical services must be configured that match both forward and reverse flows.
- I95-36591 Using connected route redistribution causes routes to be re-advertised or flapped, resulting in packet loss.
- I95-36604 Debug tables within the GUI do not honor the node selector.

I95-35873,I95-35679 Asset stuck in a connected state as a result of a corrupted linux rpmdb. The issue requires the system be updated to the 128T-installer version 2.6.1 (see IN-267. If the conductor is used to upgrade systems, the latest installer will be updated from the repository being used. If the systems do not have access to the 128T public repositories, the repository being used should be updated with the 128T-installer 2.6.1 version. With the correction of this issue, the PCLI command
send command yum-cache-refreshhas been updated to perform the rpmdb repair if the rpmdb is corrupted.
Until the system is upgraded to 128T 4.5.0 and 128T-installer 2.6.1, the issue can be mitigated by running the following linux commands:
rm -f /var/lib/rpm/__*

- I95-36146 Non-PCLI commands, such as pagination responses, are incorrectly stored in command history.
- I95-36283 The 128T router asset state is stuck on its current state.
Conditions: The following log message can be seen:Until the system is upgraded to 4.5.0, this issue can be mitigated by restarting the salt-minion service by executing
TypeError: heap argument must be a list
systemctl restart salt-minionon the Linux shell. If not manually restarted, the salt-minion watchdog will also restart the salt-minion after one hour.
- I95-36356 Loading a configuration that changes the BGP graceful-restart restart-time may cause a highway process crash if a subsequent graceful-restart timeout occurs.
- I95-33004 RoadRunner Removed The RoadRunner process collected anonymous information from the router and sent it to 128 Technology for storage and analysis. This helped inform and allows 128 Technology to support and improve the 128 Networking Platform. The anonymous data collection tool RoadRunner has been removed from the product.
- I95-35629 The threshold for broadcast announcement for concurrent PCLI sessions has been increased from 4 to 10 as a result of I95-28366.
- I95-36525 TLS 1.0 is no longer supported.

Corrective Action: No action required. The webserver will immediately restart.
I95-33560 When upgrading an HA conductor to version 4.4.0 or later there is a compatibility issue due to an upgrade of the asset provisioning software. This results in a reported asset error that will persist until the two nodes are upgraded to the same version.
Symptom: This error is seen during the upgrade of an HA conductor pair to version 4.4.0 or later. An upgrade of a single standalone conductor node will not see this error. The following error will be reported by the node running software version earlier than 4.4.0:
"128T highstate: ["Rendering SLS '128T:reverse_ssh' failed: Jinja variable 'dict object' has no attribute 'iteritems'"]"
This error can be viewed by running the following PCLI command from either node:
show assets <asset-id>. Where asset-id is the asset-id of the node running pre 4.4.0 version that has not yet been upgraded.
Corrective Action: This error is transient and will only persist for the duration of the upgrade. The error will not self-correct. Continue to upgrade the second conductor node. After upgrade, verify that there are no asset state errors.
I95-37687 PCLI configuration change flag
*may persist in the active PCLI session after a configuration commit operation.
Corrective Action: Exit and re-enter the PCLI after a commit to remove the flag.
- I95-37752 A race condition exists when a session is manually deleted through the
delete sessionsPCLI command; interim IPFIX record generation or HA session synchronization may cause the highway process to fault.
