Zombie processes occupy the system process table without using CPU or RAM, risking PID exhaustion. This guide explains how to trace defunct processes to their parents and clear them.
Learn how to use the uWSGI Cheaper subsystem to dynamically scale Python worker processes, reducing memory overhead without sacrificing performance during traffic spikes.
Learn how to use uWSGI Emperor mode to dynamically manage multiple Python applications, implement privilege separation, and monitor worker health using stats sockets.
In environments with low-traffic workloads, reducing the memory footprint of uWSGI is a priority. The cheaper subsystem allows the server to scale down the number of worker processes when demand is low, rather than maintaining a static pre-fork model defined by the processes directive. While the busyness algorithm provides a mechanism for dynamic scaling, th
Process Management and Socket Persistence In production environments, uWSGI is frequently configured with the master and vacuum options to ensure worker lifecycle management and the removal of Unix sockets upon termination. While these settings function predictably during manual restarts in local development, production deployments often rely on signal-based
Graceful Process Migration in Perl When migrating or updating a small Perl application deployed via a PSGI interface, the goal is to replace the running process without dropping active connections. While pre-forking servers like Starman support signal-based management, the interaction between the master process and worker children during a reload can introdu
