Support Tools Plugin System Info View excessive memory usage

Problem

BitBucket Server utilizes the System Info View. When it comes to rendering this page, on an instance with large number of projects/repositories, the size of the generated request can grow to a large extent, in some cases resulting in out of memory errors.

Workaround

• Analyze the heap dump and identify if the heap is utilized to a class named - org.apache.catalina.connector.Response, which is initiated by the STP (Support Tools Plugin).
• Verify that the instance has a large number of repositories and other metadata rendered on the System Info View (or by the application.xml file in the Support Zip).

If the above two is present, the workaround is to increase the heap allocation, so that the response can fit into memory.
