4.14.16 The Error Messages "write() File too large" and "The daemon failed to write job net output information" are Displayed [UNIX Versions]

Error message

MpJobsch: ERROR: write() File too large

MpJobsch: ERROR: 0037: The daemon failed to write job net output information.

Applicable versions and levels

Action

Points to check

Was in excess of 2 GB written to the previous log file of the job, so that a large volume of outputs was performed by the job?

[Previous log file of the job]

"project name_job net name.log" (*1) in the database directory

*1: In V13.3.0 or later, the file name is <project name>_<job name>_<nn>.log (nn is any number)

Cause

If the file size exceeds 2 GB, the write() system call returns the error "File too large".

In the previous log file of the job, the standard output and the standard error output are written to each temporary file, and join at the point when the job ends. When they join the previous log file of this job, the error also occurs when 2 GB is exceeded. If the file size has exceeded 2 GB, the processing will continue, however the content of the previous log of the job cannot be referenced.

Action method

The size of the previous log file cannot be extended. Ensure that the file size does not exceed 2 GB.

For example, consider selecting the Do not save standard/error output option in the Add/Change - Job window, or reducing the volume of logs that are output by the job, so that the previous log file of the job does not exceed 2 GB.

Information

The previous log file of the job is created for each job net.
