我有一个OpenCart网站，其中包含一堆带有加密文件的插件。随着我添加越来越多的产品（目前为150k），它变得越来越慢了。慢点。由于我无法更改查询（文件已加密），我不得不更改我的一些表格＆＃39;存储引擎到MEMORY。我的查询时间从50秒到2秒。
但是有一个新问题。如果我尝试在DB服务器崩溃的同时打开4或5页。这是一个托管的VPS，因此我无法访问所有内容。托管的支持根本没有帮助，并告诉我不要使用MEMORY，因为它不兼容！
我在localhost上有完全相同的设置（唯一不同的是webhost是MariaDB但我在我的localhost上使用MySQL）并且我无法重现错误，我尝试了多少。
以下是OpenCart中的错误日志：

我对DBs＆amp ;;不太了解我完全迷失在这里。如果这是与内存相关的问题，那么我可以更改变量或设置，以便数据库等到第一次查询完成后才会发生。当有足够的RAM时继续？
