@dhiltgen commented on GitHub (Sep 25, 2024):

Can you clarify? When you say "system crashed" was there a kernel panic resulting in a reboot of the system, or did ollama crash? Ollama starts multiple threads downloading in parallel which can stress slow network connections (#2006 tracks rate limiting support). This could cause a remote ssh session to slow or hang during downloads, but it should recover after the download completes.

We fixed a bug in the last release where on retries during pull file descriptors were being left open, so on a very slow/flaky network, this may result in open socket exhaustion. Please give 0.3.13 a try and let us know if that resolves your problem.

If you still see the problem on the latest release, let us know and I'll reopen.

It looks that an invalid cronjob caused this, i am using ollama a little bit and dont experience any crashes at all. Its working fine
