------------------------------------

Indeed, looks like a duplicate.
I was not able to reproduce this issue using JBoss 7.1.3.

> We're running 7.1.1, with a patch applied for REMJMX-45 to limit the worst leaks coming from the JMX subsystem.
> However, even with this patch applied we can only survive for a few days in a production-like scenario.
> Inspection of the out-of-memory heap dumps shows a large accumulation of entries inside {{java.io.DeleteOnExitHook}}, all having values like "{{C:\jars\jboss-as-7.1.1.Final\standalone\tmp\auth\challenge-4303257}}".
> Given sufficient JMX connections made to a running instance of 7.1.1, this will at some point exhaust the JVM heap. Typically the paths will be longer than the example above, accelerating the process.
