Products

• Workload Automation Agent

Issue/Introduction

When resubmitting a job it aborts with SUBERROR state with a permission denied error.

CAWA_E_20002 Unable to create STDOUT: Permission denied. Error code: 13

 

Environment

RHEL 9 Only

 

Cause

Due to changes in sysctl configuration under RHEL 9 OS.

Resolution

This is a behavior change in RHEL 9 in which the vendor has provided a kernel parameter to control the behavior similar to previous versions. 

Please refer the below kernel document: https://www.kernel.org/doc/Documentation/sysctl/fs.txt

As per the above kernel document,

1. Add the below parameter in /etc/sysctl.conf
   fs.protected_regular=0
2. Reload the kernel parameters and the problem should be fixed as we tested locally.
   sysctl -p /etc/sysctl.conf
3. Restart System Agent.
