Dear EVE-NG support team,

I'm trying to work on a topology of decent size (20 nodes), but I'm having issues while trying to export startup configs.
I get "Failed to lock the lab (60061)" message. It happens even if I have only one node powered on.
Is there any way to get around that?

Thanks!

Problem sovled.

pls tell how did you sovle it?

I have same error in response when I try to add node using REST API.
After that even when I try to add node using GUI in the same lab I had same error in GUI.
What is the issue ?

go inside eve:
opt/unetlab/labs

and check if your labname has not such file yourlabname.locked.
These locked files must be deleted
