A CloudBees Build Acceleration program discovered a file that was too large for its intended purpose. A CloudBees Build Acceleration program successfully opened the named file for reading only, an then discovered that it was too long to read fully into memory. The purpose CloudBees Build Acceleration had in mind for that file required reading it into memory, and it was too big for that. In this case transient memory availability issues may have been a factor in the file being considered “too large”.
A file CloudBees Build Acceleration expected to have a reasonable size instead had an excessively large size, at least at the moment. (By contrast, EC5005 concerns structural limits.)
First consider whether the content of the file was correct. If not, then correct it. But if the file was correct, then consider freeing up available memory, either in other programs or in other tasks performed by the same program. Possibly going to a 64-bit variant of the relevant CloudBees Build Acceleration program might help.
