Debug logs not getting stored when triggered from non-apex context and running into an apex limit

Apex , VisualForce , Spring 19

Fixed - Spring '19 Patch 8.0

Debug logs are not getting stored when they are larger than a few MBs, the apex execution runs into an apex limit/exception (e.g. Too many SOQL queries) and the execution was triggered from a non-apex context (e.g. visualforce).

- A non-apex context (e.g. visualforce) execute an apex code.
- Apex code runs into an apex limit/exception (e.g. Too many SOQL queries)
- And debug log size is larger than a few MBs then the debug logs are not available to download.

- Follow below steps:
1. Enable a trace flag using the Debug Logs UI (Setup > Monitor > Logs > Debug Logs).

2a. Directly run the apex code that you want to debug using Tooling API (

2b. Or run the apex code using sfdx cli command: sfdx force:apex:execute --apexcodefile (

2c. Or writing an apex test that runs that code and run it using the Apex Test Execution UI (Setup > Build > Develop > Apex Test Execution)

3. Refreshing the Debug Logs UI should now show a list of the debug logs generated from step 2 and users should be able to view/download them.

Is it Fixed?
