Problem Statement:
In containerized environments, especially with operators like Spark that dynamically generate multiple pods with extensive environment variables or argument lists, the hard limit imposed by ARG_MAX causes job failures. Although workarounds like periodic cleanup or restructuring workloads exist, these are not sustainable or production-friendly solutions.

Current Behavior:

• ARG_MAX is statically defined at kernel build time (#define ARG_MAX 131072).
• The limit cannot be adjusted at runtime, even through ulimit or sysctl.
• When exceeded, processes fail with argument list too long errors, impacting container startup and workload automation.

Proposed Enhancement:

• Introduce a kernel tunable (sysctl or cgroup-level parameter) to adjust the maximum allowable argument list size (ARG_MAX) within safe boundaries.
• Alternatively, provide documented best practices or kernel enhancements for better handling of large argument/environment spaces in containerized workloads.

Business Impact:

• Affects OpenShift customers using Spark and similar data-intensive operators.
• Requires manual or cron-based workarounds, which are operationally inefficient.
• A configurable or adaptive mechanism would improve reliability and scalability in modern containerized applications.
