WordPress Max User Connections Error Resolved in 1.5 Hours — After-Hours Support at 10 PM

A client reported that their WordPress website was completely down, preventing users from accessing the site. Our development team immediately investigated the server, application, and database logs to identify the root cause. 

We discovered that the website had reached the MySQL maximum user connection limit, caused by repeated database operations from a WordPress plugin. Our developers identified and fixed the underlying database issue and restored the website within just 1 hour and 30 minutes. 

Result: Website restored, database errors resolved, and normal operations resumed. 

Client reported an outage → GTPL investigated → found the root cause → fixed it → website restore 

How We Investigated

Our development team immediately checked the server and WordPress/PHP error logs. 

The investigation revealed that the database had reached its MySQL max_user_connections limit, preventing WordPress from establishing new database connections. 

Further investigation showed repeated database errors related to the Broken Link Checker plugin. The plugin was repeatedly attempting a database schema update, which was failing because of an issue with the plugin’s database table structure.

Root Cause

The issue was traced to an inconsistency in the Broken Link Checker database tables. 

Repeated failed database operations were consuming database connections and eventually caused the website to reach the configured maximum user connection limit. 

Our Solution

  1. Our developers: 
  2. Reviewed the server and WordPress/PHP error logs.  
  3. Identified the database connection limit issue.  
  4. Traced the repeated database errors to the Broken Link Checker plugin.  
  5. Investigated the plugin’s database table structure.  
  6. Corrected the affected database column configuration.  
  7. Monitored the server and error logs after applying the fix.  
  8. Deactivated the plugin because it was not required for the website’s current operations.

Result

Website Restored Successfully 

After implementing the fix, the website became accessible again and the repeated database errors stopped. 

The team also monitored the website after the fix to ensure that the issue did not recur.
