opencode(>=1.18.12) run as server crashed again and again

Description

I wrote a run_opencode.sh script to start the opencode serve command and automatically restart it on abnormal exit. Over the past few days, opencode has crashed multiple times.

#!/bin/bash
while true; do
    /root/.nvm/versions/node/v22.22.1/bin/opencode serve --hostname 0.0.0.0 --port 4096
    echo "$(date): opencode exited, restart..." >> /var/log/opencode.log
done

(base) root@develop:/opt# cat /var/log/opencode.log
Fri Jul 31 11:41:03 AM CST 2026: opencode exited, restart...
Mon Aug  3 10:31:09 AM CST 2026: opencode exited, restart...
Tue Aug  4 08:46:07 PM CST 2026: opencode exited, restart...
Wed Aug  5 12:05:55 PM CST 2026: opencode exited, restart...
Thu Aug  6 10:10:43 AM CST 2026: opencode exited, restart...

crash log：
