    Description

      I've had server running for 2 days and had a lot of requests to create JDR. Couple of times the server did not responded with generated file and in server log there was java.lang.OutOfMemoryError: Java heap space.
      The server was still running and no other errors were thrown. Another generating of JDR failed as well. I had to refresh the browser and then JDR was generated.
      From what I googled it seems that when new JDR is generated it spawns new thread which will throw this error, is then closed and server continues on running.

      Two possible ways of dealing with this:

      1. Send to UI that OOM happend and suggest to restart server
      2. Send to UI that generating of JDR failed and suggest resending request

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
