PET exited unexpectedly with code null, signal SIGTERM

What it is probably relevant, is that my workspace has two nested uv environments.

├── .venv
├── .vscode
└── zarr_era5
    ├── .venv
    ├── .vscode
    └── zarr_era5.py

[karthiknadig]

Thanks for the report. I tried to repro this in a Linux container with a root .venv, a nested zarr_era5/.venv, and a /home/... symlink to a /data/... workspace; pet resolve, configure, and refresh all found both uv envs quickly.

Your log looks like PET is being killed after repeated configure timeouts rather than crashing directly. Could you check two things on the remote host?

1. Is /home/steliosvito/Private/hrvpp2 a symlink or mount to /data/users/Private/user/hrvpp2?
2. How long does this take?

time find /home/steliosvito/Private/hrvpp2 -name .venv -type d -print

Also, does narrowing/removing the **/.venv environment-directory setting avoid the timeout?
