NSO - Juniper QFX false commit failure problem

[fatbatbtegitim]

Hi all,

We are facing issue between NSO and Juniper QFX series devices. When we done commit from NSO we get back response is "commit failure" while commit was succeed on the QFXs.  Tested NSO version is 5.3 and junos versions are 18.4 and 19.4. All detailed trace logs attached from both sides

Below, you can find basic commit failure scenario

admin@ncs% set devices device dc1-leaf2 config configuration system host-name AAA
[ok][2020-08-31 10:37:10]

[edit]
admin@ncs% commit
Aborted: dc1-leaf2: "commit-results" cannot occur here as a child to 'rpc-reply'.
[error][2020-08-31 10:37:15]

while on the switch side (has been already commited);

{master:0}[edit]
root@AAA# show | compare rollback 1
[edit system]
- host-name DC1-LEAF2;
+ host-name AAA;

Could you try to increase your Juniper QFX read/write timeout

devices device <device-name> 
read-timeout 60
write-timeout 60 
disconnect 
connect
