我使用Airflow（docker容器）运行R脚本。我收到以下错误。

错误代码为split(es6, (0:(nrow(es6) - 1)%/%50))。数据帧es6大约有1096行和20列。
我有时无法通过Airflow重现成功而失败的错误。 （而且，当我通过Rstudio Sever运行代码时，代码就可以工作。）
我怀疑服务器内存不足可能是原因。我的linux服务器总共有8GB内存。当我在运行任务时检查内存时，它有大约1700MB的可用空间（使用free -m命令）。
我在互联网上搜索，有人认为这种错误可能是由于该函数的错误引起的，即split。
编辑：
更改为split(as.data.frame(es6), (0:(nrow(es6)-1) %/% 50))之后。新的日志：
