Subject: "java/lang/OutOfMemoryError" when running agent around 15 times.
Feedback Type: Problem
Product Area: Domino Server
Technical Area: Application Development
Platform: Windows
Release: 8.5.3
Reproducible: Always

Hi There,

I am writing a Java agent which runs on the Domino server using the code below. I am using the JODConvertor v2.0 Java library "" which leverages to do some .doc to .pdf conversion on a couple of documents with files attached.

However, when I run the agent roughly 15 times I get a "java/lang/OutOfMemoryError". The error trace looks like the below. Just wondered if anyone could shed any light on this issue. assume it is because I am connecting to an instance running on port 8100 and somehow this remains open and in memory and then crashes the JVM.

Also please note it is only the JVM that crashes the server continues to function after that, minus the JVM of course.
