It was observed that in Space 24.1, DMI session not getting cleared when a Device in Space is put in RMA or gets deleted from Space .

The DMI sessions remains on the BNG and on the Space node.

• In the App01 node the device ssh connection list as below :

# netstat -anlp | awk '{print $5}' | grep ":22" | uniq -c
1 <Dev1_ip>:22
1 <Dev2_ip>:22

• RMA for Dev1 and Dev2 was performed

• The connections are still intact in the same node

# netstat -anlp | awk '{print $5}' | grep ":22" | uniq -c
1 <Dev1_ip>:22
1 <Dev2_ip>:22

• Could see, after performing the RMA, the ssh connection is not removing from the node.
  Also space didn't  receive the device delete command to terminate the ssh connection.
  Same can be verified in server.log as below :

# grep "receive device delete command"  /var/log/jboss/servers/server1/server.log
#

Fix: This issue related to RMA/Delete device (per node basis) is fixed on 24.1R4.399588 in an 8-node setup. In the fixed versions, DMI session are getting deleted properly when device gets deleted from Space or put in RMA.
Workaround: It is recommended to select devices individually (single-node selection) when performing RMA or Delete operations for earlier versions.
