我有一个使用5个不同数据库的项目（oracle，mssql，ibm Informix等，......和...... mysql）
每次超时cron都会将数据导入MySQL。不幸的是，我们有一个非常庞大的cron脚本，可以导入近400 k行。我通过小包导入数据，但是当cron运行这个脚本时，MySQL需要大约2 GB的内存，并等待下一个调用。比需要多2 GB，这在MySQL崩溃之前会重复。
我们已经遇到了MySQL innodb损坏并从1到4运行恢复模式以重启数据库的问题。
服务器总内存为12 GB。
我们对/etc/my.cnf.d/server.cnf的配置如下所示：
#
# These groups are read by MariaDB server.
# Use it for options that only the server (but not clients) should see
#
# See the examples of server my.cnf files in /usr/share/mysql/
#
# this is read by the standalone daemon and embedded servers
[server]
# this is only for the mysqld standalone daemon

如果需要任何信息来找出发生这种情况的原因，我会提供。
请！帮我找出解决方案！我应该重新安装MySQL，还是仍然可以通过配置修改解决???
