Very partial answer:

Error -116 is "stale file handle", as you can find for example if you go through the errno.h header files on your system.

This happens in a write syscall, as the error message says.

For details about "stale file handle", see e.g. this question.

So you need to figure out on which file that happens and what directory etc. gets deleted beforehand so you end up in a situation where you get this error message. The usual way to do this is to add debugging messages to your code, until you have enough information to track the problem down. (This kind of debugging is impossible to do remotely by Q&A on this site).
