Nice2 Runtime Errors

Wkhtmltopdf Out-of-Memory

Error:

RuntimeException: wkhtmltopdf exited with code 139: Error running wkhtmltopdf

Wkhtmltopdf <0.12.4 shows this error:

java.lang.RuntimeException: Error running wkhtmltopdf

Cause

The wkhtmltopdf process has been killed by signal 9 (SIGKILL) [1]. This most likely happened because of an out-of-memory error.

Solution

Option 1: Reduce Memory Usage

  • Try to reduce memory usage by …

    • … splitting the report (i.e. select fewer entities at once).

    • … reducing the size of the report resources (e.g. smaller image resolution, no custom font).

    • … simplifying the report (e.g. remove headers/footers, different corporate design).

    • … limiting the number of reports generated concurrently.

Option 2: Increase Available Memory

Increase requested memory to ensure the instance is moved onto a node with enough free memory available and/or adjust the memory limit to ensure it’s not hit when generating reports. [2]
