File Content Extraction 26.1
Filter SDK C++ Programming Guide

# System Requirements

File Content Extraction uses shared memory to communicate with its child processes, and requires 8MB per child process. A session that includes both filtering and extraction therefore requires 16MB in total. You should ensure your machine has an appropriate amount of shared memory for the number of sessions and threads you expect to run.

This means that you might need to override the default shared memory limit. This is unlikely to be necessary on a bare metal operating system where the default shared memory size is typically half the system RAM, but in a containerized environment (Docker/Podman/Kubernetes) the default is typically only 64MB.
