我突然开始在应用程序中收到很多 SignalException:SIGTERM 异常，显然来自 mysql。堆栈跟踪像

vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:217
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:217:in `log'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:608:in `select'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all_without_query_cache'

或者

vendor/rails/activesupport/lib/active_support/buffered_logger.rb:63
vendor/rails/activesupport/lib/active_support/buffered_logger.rb:63:in `add'
vendor/rails/activesupport/lib/active_support/buffered_logger.rb:71:in `debug'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:196:in `log_info'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract_adapter.rb:218:in `log'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:323:in `execute'
vendor/rails/activerecord/lib/active_record/connection_adapters/mysql_adapter.rb:608:in `select'
vendor/rails/activerecord/lib/active_record/connection_adapters/abstract/database_statements.rb:7:in `select_all_without_query_cache'

我有点难过。任何想法从哪里开始挖掘？

你在什么平台上运行，你运行的是什么版本的 MySql？听起来 mysql 客户端库或 mysql 服务器可能已损坏。另外，这是一个新的应用程序还是一个已经运行了一段时间没有问题的应用程序？

重新安装 MySql 可能是您最好的机会，但在您这样做之前，请尝试使用替代的 mysql 适配器：mysql2 和 ruby​​-mysql。你可能会有一点运气，可以节省很多时间和麻烦。
