Symptom

Build requests for certain DCs fail repeatedly with OutOfMemory exceptions.

Solution

Change the CBS settings or inform its administrator:

  1. Open the Visual Administrator.
  2. Check the BUILD_TOOL_VM_ARGS property of the CBS under Server > Services > Component Build Service/Properties. It should contain the option -Xmx1000M (corresponding to 1GB of memory for each build process). 
  3. Temporarily reduce the number of concurrent build tasks. Decrease the value of the property threadPoolSize under Server > Services > Component Build Service/Properties and restart the CBS service.

OSS note 1402901 provides more background information on the impact JVM settings have on the DC build in CBS.

Additional Information

Most probably there are too many build processes that concurrently try to build large components.
