Alarms are listed alphabetically.
A content scanning engine is stuck. This alarm will display even in the event of a single engine being stuck while others are still processing correctly.
You are not able to manually clear this alarm. The alarm will be cleared when stuck engines are restarted or there is a proxy restart.

A log file in /var/log/cs-gateway or /var/log is bigger than 50 MB. This alarm condition can arise if a system service is repeatedly recording warning or error messages in its daily log file. CREATE TABLE `licenses` ( `id` int(11) NOT NULL
Critical Information Protection Server unreachable. See Messaging Service log for more information.
CPU idle is 2% or less for a sustained period. The system cancels the alarm when CPU idle increases to 7% or more for a sustained period. Ignore this alarm unless it persists for more than ten minutes. Conditions that can trigger this alarm are:
Occupied disk space has reached 95% or more for a sustained period. The system cancels the alarm when disk space drops to 92% or less for a sustained period. The alarm description may also include (main) or (data). If you are looking to implement a system
Occupied disk space has reached 85% or more for a sustained period. The system cancels the alarm when disk space drops to 82% or less for a sustained period. The alarm description may also include (main) or (data).

If you are looking to implement a system found on GitHub, understanding the architecture is key. A robust system typically consists of two parts:
Searching "php license key system" on GitHub yields thousands of results. The "hot" status is determined by recent commits, stars, forks, and activity. Currently, the ecosystem is moving away from silent validation (where the license is checked once locally) to live heartbeat verification and entitlement servers.
Why GitHub? Developers prefer open-source boilerplates for licensing because building a crypto-secure license generator from scratch is prone to math-based vulnerabilities. Current trending repositories emphasize:
Most popular repositories on GitHub share a similar architecture. A typical system consists of two parts: the Client Side (the plugin/script) and the Server Side (the license manager).
Before diving into the repos, here’s what the developer community is looking for in 2025:
To build a system that matches current GitHub trending standards, follow this blueprint.
You cannot call the license server on every page load (performance nightmare). The "hot" pattern is to validate once, store the result in a signed session or local database, and re-validate every 24 hours.
This validator requires no outbound HTTP by default, but includes a revocation check CDN.

The SMTP Alert Transport is not running. This is usually a short-lived alarm condition, and is cleared when the next system status check occurs. Ignore this alarm unless it persists for several minutes. See Managing Services for more information.
Conditions that can trigger this alarm are:
The managed list download has failed. Conditions that can trigger this alarm are:
Memory usage has reached 97% or more for a sustained period. The system cancels the alarm when memory usage drops to 94% or less for a sustained period.
Memory usage has reached 90% or more for a sustained period. The system cancels the alarm when memory usage drops to 87% or less for a sustained period.
An exception has occurred while purging the Web Audit database or while trying to publish data to the database.
