> When using ARI4Java bindings and their Dial() method, Asterisk leaks (fails to close?) an eventfd, leading to a crash once the underlying OS' ulimit is reached.
> This behavior is only seen using dial(). When using originate(), asterisk behaves correctly.
> This bug is reproducible on Asterisk 13x and 14x using Ari4Java 0.4.3 and 0.4.4 and ARI protocol version 1.7 through 1.10. We have been unsuccessful in testing 2.0.0 or 3.0.0 protocol variants, thus we cannot guarantee this behavior exists in the 2x and 3x protocol branches.
> While the actual bug may be in Ari4Java, it is arguable that a REST interface should not be allowed to cause the host to leak file descriptors as this a potential DOS attack (or worse). This is thus clearly a bug in Asterisks implementation of ARI and requires immediate attention.
> We have filed an issue with Ari4Java as well.
