Failed rendering of pages with a large number of static macros

Issue Summary

Pages with a large number of static macros do not render reliably. 

Steps to Reproduce

1. Add 100 static macros to a page.
2. View the page.

Expected Results

The page renders reliably.

Actual Results

The page intermittently fails to render. See screenshots.

When inspecting the developer console, the following response can be seen in the <site>/cgraphql?q=MacroContentRendererQuery requests:

{"errors":[{
"message":"Exception querying the remote GraphQL service: io.atlassian.platform.micros.asynchttp.UnexpectedHttpStatusResponseException: Unexpected status code 500",
"locations":[{"line":2,"column":3}],
"path":["contentRenderer"],"extensions":{"statusCode":"500"}}],
"data":{"contentRenderer":null}}

In the logs on the Atlassian end, the error relates to the following:

Could not open Hibernate Session for transaction; nested exception is net.sf.hibernate.exception.GenericJDBCException: 
Unable to acquire JDBC Connection

Workaround

Currently there is no known workaround for this behavior. A workaround will be added here when available
