Description
The emake client failed to write a new parse result into a cache slot directory. This error is fatal.
The final portion of the error message is provided by the operating system, and indicates what exactly went wrong.
Reasons
The emake client maintains an “asset directory”, which provides a memory of past builds to help future builds. Certain subdirectories of the asset directory correspond to cache “slots” used by Parse Avoidance.
Because emake wanted to update a Parse Avoidance cache slot, it created a new temporary directory to represent the new state of that slot, and a “key” file in that directory. It then tried to write a new parse result into that directory, but failed to open the file for writing.
The most likely reason would be lack of disk space, but see the trailing portion of the error message for the specific error reported by the operation system.
