廚師服務器例行崩潰

Question

我們有一個獨立的廚師服務器安裝（v 12.1.2）。它已經運行好幾個月了，但最近它已經開始每天幾次崩潰。查看日誌，看起來好像「opscode-erchef」服務每天崩潰幾次。這是從Opscode公司-erchef崩潰日誌：

Rettarting opscode-erchef followed by opscode-expander service brings it back again. 

誰能告訴，在會崩潰什麼情況下Opscode公司-erchef服務？當CPU發生故障時，我看不到任何緊張情緒。所以服務器資源似乎不成問題。

謝謝！

這個錯誤與RabbitMQ和工人有關;嘗試增加可用於RabbitMQ的連接數量或調整超時或增加連接。

rabbitmq['rabbit_mgmt_http_max_count']

對於被使用的RabbitMQ的管理插件的HTTP連接池的最大工作數。默認值：100。

rabbitmq['rabbit_mgmt_timeout']

對於被使用的的RabbitMQ管理插件的HTTP連接池的超時。默認值：30000.
