Goldstein Lyor commented on SSHD-340:
-------------------------------------
{quote}
For example Nio2ServiceFactory does perform a group.awaitTermination during
doCloseImmediately() which is wrong
{quote}
I am not so sure - there is a (cryptic remark) that saysÂ
{code:java}
// if we protect the executor then the await will fail since we didn't really
shut it down...
{code}
in any case, the {{awaitTermination}} call is executed only if
{{isShutdownOnExit}}
> Hanging threads left working when server is shut down

> Key: SSHD-340
> URL: https://issues.apache.org/jira/browse/SSHD-340
> Project: MINA SSHD
> Issue Type: Bug
> Affects Versions: 0.12.0
> Reporter: Sampo Savolainen
> Priority: Major
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> SSHD fails to stop properly due to errant threads. I've attached a thread
> dump from a point of execution where everything should have been cleaned up.
> The hanging threads happen only if the server has accepted connections and
> they do not hang forever, they seem to stop themselves after a minute or so.
> This might be an executor pool which is not shut down correctly.
> Earlier versions (0.8.0 and 0.9.0) did not exhibit this behavior.
