cPanel server administration challenge

we've been running our website maintenance & cpanel management services for a while now, primarily automating updates and basic resource monitoring with custom scripts. it's mostly been stable, but we're hitting a wall with intermittent issues that are tough to debug, specifically around server administration tasks.

the main problem revolves around a specific daemon or cron job that's supposed to handle routine cpanel server administration like log rotation and temporary file cleanup across multiple client sites. sometimes, it just hangs or creates zombie processes, leading to resorce spikes and occasional service interruptions for no clear reason. we've checked logs, permissions, and memory limits exhaustively, but the pattern is elusive.

i'm trying to figure out if there's a more robust, perhaps event-driven, approach to managing these core server administration functions within a cpanel environment, especially when dealing with such a diverse set of client configurations. has anyone successfully implemented a highly resilient system for this without resorting to full-blown custom server builds?
