I currently observed that running GPT from different users on a Linux machine does somehow create problems. When a single GPT process is running and another user starts a GPT command, often the error message:
However, as soon as the process is finished, another GPT can be started without issues.
Is it possible to alter some config files etc. to prevent this error from happening?
Did you install SNAP separately for each user or are the users sharing a common install? In our lab each user has their own installation and we have not encountered conflicts such as you have, only the expected resource limitations of total RAM in the machine.
I guess this is only happening when you use Sentinel-2 data.
There is a check which leads to this error.
@obarrilero Can you check why this happens and if it can be avoided?
@c3po SNAP and gpt have not really be developed with the idea in mind to have multiple instances running at the same time. So it might work or it might not. For the future, we have ideas to better separate the instances. But this doesn’ help you now.
It could help you if you specify a different user directory for each user/instance.
You can add to the gpt call -Dsnap.userdir=Path/to/user_dir
Hope this helps.
