Le backtesting peut générer des logs, mais il n'y a pas de sortie de log dans le trading réel. Je vois l'erreur suivante. Quelle peut en être la raison ?

“一个database connect，既有查询又有更新（不同的statement，且不论顺序），执行完之后，不关闭，
会产生一个扩展名为s3db-journal的（临时）文件，
若再次使用该connect执行更新，则产生“unable to open database file”的异常。 
所以，一个connect执行完之后要么close，要么自己处理临时文件。”

可能是这个原因。
方便发下代码么？

谢谢梦总。问题已经解决了，原因是我的运行托管者的服务器磁盘空间满了。清除了后就可以了，谢谢啦。
