To fix System.LimitException in Apex triggers, you must diagnose and remediate governor limit violations by consolidating SOQL queries, removing DML inside loops, and applying bulk-safe processing patterns.

Apex governor limit violations occur when transactions exceed SOQL, DML, CPU, or heap limits due to inefficient bulk processing, typically caused by SOQL-in-loop patterns, excessive DML statements, or improper callout usage.

Optimize SOQL and DML limits in synchronous Apex controllers by consolidating queries into maps, using aggregate queries, executing single-batch DML operations, and offloading heavy processing to asynchronous queueable jobs.

Yes, you can prevent CPU and heap limit exceptions by offloading resource-intensive logic to asynchronous Apex jobs like batch or queueable classes, which have higher governor limits and support heap minimization techniques.

You can write unit tests that measure Apex governor limit consumption by using built-in limit methods to reset and track resource usage, validating that your trigger and service designs remain bulk-safe under load.

The best way to handle callout limits in Apex integrations is to identify improper callout usage, implement limit-aware guards, and offload long-running external requests to asynchronous processing to avoid boundary breaches.
