My Heroku application uses PostgreSQL on AWS via Spring Data JPA. Occasionally, under high load, I see errors like this:
Caused by: javax.net.ssl.SSLProtocolException: Data received in non-data state: 6

The call to JSSE is done within the PostgreSQL driver which, in turn, is done from Spring Data JPA. Any idea what I can do, if anything, at the application level to address this?
Related: This question Program never throws exception when debugger is attached has a similar symptom, but is triggered from the AWS SDK and the suggested solutions do not apply.
