我运行的是2008年以来非常老的Zope应用程序，崩溃后我不得不在新服务器上重新安装该应用程序。我已经很难重新安装这些旧的Zope模块，终于重新工作了。但是，我经常遇到以下错误，该错误似乎与模块ZMySQLDA有关：
Traceback (innermost last):

zope日志中的错误：

我已经检查了MySQL中的max_package和timeout变量并增加了它们。 MySQL日志中没有错误。因此，该错误最初似乎与MySQL没有关系。其他有关stackoverflow的文章中提出的解决方案无法解决此问题。
我可能不应该再运行这个过时的应用程序，但是它仍然非常重要，不能轻易替换。任何帮助将不胜感激。
