[hansstimer]

On the remote server (version 0.145.1) I've been seeing crashes too. Seen this in the system logs:

Out of memory: Killed process 7287 (zed-editor) total-vm:32031012kB, anon-rss:15423292kB, file-rss:2560kB, shmem-rss:0kB, UID:1000 pgtables:38924kB oom_score_adj:0

As one might imagine, the machine locks up until it unwinds the process.

I'm going to close this because we changed how remote development works completely: https://zed.dev/docs/remote-development Let's open another issue if this happens again.
