Airflow 网络服务器关闭

Question

我的 Airflow 网络服务器在格林尼治标准时间 16:37 左右的同一时间突然关闭。我的气流调度程序运行良好（没有崩溃）任务仍然运行。

除此以外没有太大的错误。

Handling signal: ttou
Worker exiting (pid: 118711)
ERROR - No response from gunicorn master within 120 seconds
ERROR - Shutting down webserver
Handling signal: term
Worker exiting
Worker exiting
Worker exiting
Worker exiting
Worker exiting
Shutting down: Master

是记忆力的原因吗？我的网络服务器 cfg 设置是标准的。

# Number of seconds the webserver waits before killing gunicorn master that doesn't respond
web_server_master_timeout = 120

# Number of seconds the gunicorn webserver waits before timing out on a worker
web_server_worker_timeout = 120

# Number of workers to refresh at a time. When set to 0, worker refresh is
# disabled. When nonzero, airflow periodically refreshes webserver workers by
# bringing up new ones and killing old ones.
worker_refresh_batch_size = 1

# Number of seconds to wait before refreshing a batch of workers.
worker_refresh_interval = 30

更新：好的，它不会每天崩溃，但今天我有gunicorn无法重新启动日志。

ERROR - [0/0] Some workers seem to have died and gunicorn did not restart them as expected

[严重] 工作线程超时 (pid:108237)

我得到这个，我已将超时增加到 240，是默认值的两倍。

有谁知道为什么这种情况不断出现？
