Proactive Alert Monitoring: Concurrent UI Errors

Publiceringsdatum: Aug 31, 2023
Beskrivning

Salesforce limits the number of Long Running UI transactions in your org. Once this limit is exceeded, you may encounter Concurrent UI Errors, caused by subsequent transactions’ attempts to process whilst the limit is exceeded. By default this is typically set to 25 long running UI requests for 10 seconds.

The Signature Success plan’s Proactive Monitoring product will monitor for, and alert you to, sustained volumes of these errors. This article outlines some scenarios to help you investigate should you receive an alert. In addition, on the Salesforce Help site Designated contacts and above can see your realtime metrics, alerts & more.

If you receive the following error message, your organization may experience performance issues and possible service disruptions.

Full error message text:

  • 'ConcurrentUiRequests Limit exceeded'


Causes:

Concurrency issues of this type often arise due to:

  • Long Running UI requests
  • Long Running Reports,DashBoards
  • Multiple Dashboard refreshes


Note: Concurrent UI Errors may also contribute to Concurrent Apex and/or Concurrent API Errors, given the right circumstances.

Lösning

Here are some common practices & resources that may help to resolve this error.


Unnecessary Log Statements

  • Check if there are any unnecessary console.log statements while developing Lightning components (Aura, Web Components) which could lead to long running requests.
 

Poor Dashboard Performance

  • Dashboard performance depends mainly on the performance of its source reports. Source reports run themselves may also contribute to this issue. If a dashboard is refreshing slowly, each report needs to be examined to find the slow running report. Please see the Improve Report Performance article for help optimising report performance, and in turn dashboard performance.
