我刚刚将一个较旧版本的 Discourse 安装（1.9.0.beta5）迁移到了 Digital Ocean 上一台全新配置的 droplet，系统已更新至最新版本。鉴于旧版本年代久远，我原本不确定所有数据都能正确迁移，但看起来运行正常。
不过，它每隔几小时就会崩溃。
这是今天凌晨 12:57 收到的错误日志：
消息
作业异常：JavaScript 已终止（因超时或显式终止）

ok: run: redis: (pid 48) 11912s
ok: run: postgres: (pid 47) 11912s
supervisor pid: 26654 unicorn pid: 26658

config/unicorn_launcher: line 15: kill: (26658) - No such process
(26654) exiting在上午 9 点重启后，网站正常运行了几个小时后，于上午 11:04 再次崩溃。两处的错误日志基本相同。再次重启暂时解决了问题。我会持续监控，并在需要时重启，直到彻底解决此问题。
