我在R中并行运行分析。分析本身运行没有问题。我最近添加了一个参数来确定在每个节点中，代码是否在每次分析迭代结束时生成图形。这引入了一个新错误：
Error in unserialize(socklist[[n]]) : error reading from connection
每个节点的日志文件表示在绘图期间发生此错误。我尝试了对代码的轻微修改，但随着工作的出现，出现了更多的错误。
*** Error in `/usr/lib/R/bin/exec/R': free(): invalid pointer: 0x0000000000a9eaa8 ***
*** Error in `/usr/lib/R/bin/exec/R': corrupted double-linked list: 0x00007f5c3338f5e0 ***
*** Error in `/usr/lib/R/bin/exec/R': free(): invalid pointer: 0x000000000070daa8 ***
*** Error in `/usr/lib/R/bin/exec/R': double free or corruption (!prev): 0x00007f365231d220 ***
谷歌搜索表明这些错误与ggplot2函数底层的C ++代码有关，但我不知道如何开始调试R引用的编译C ++代码。
目前，我无法使用最小的示例复制错误。这个要点提供了我正在做什么/密谋的想法：https://gist.github.com/ElizabethAB/9dfc377eb7b2773c3d6e

我卸载了ggplot2并从源代码重新安装。这解决了这个问题。
