Hi, [~swd847]:

I just tried this out and the connection hangs around for 30s until the default async timeout is hit, then it goes away as expected. I tested against both 8.2.0.Final and the most recent upstream and the behaviour was the same.
The behaviour is basically the expected behaviour, because nothing catches the IOException thrown on flush the request basically hangs around doing nothing until the async timeout is hit. I could potentially forcibly kill the underling connection if a write fails, but either way the request object will be hanging around until the timeout.

As you said, if we haven't add ctx.complete after invoking ctx.getResponse().getOutputStream().flush(), the connection hangs around for 30s until the default async timeout is hit, then it goes away as expected.
However, if we add ctx.complete after invoking ctx.getResponse().getOutputStream().flush(), the IOException will thrown during invoking the ctx.complete.
Here's the stacktrace as follows:

Finally, the current socket connection in JVM will keep in alive because of the above thrown exception. We did investigate the above stacktrace and found the IOException will thrown by HttpResponseConduit.write before close the socket connection in JVM. in the other words, there's no operation in undertow to close the socket connection in JVM if the IOException were thrown by HttpResponseConduit.write in invoking the ctx.complete.
Thanks.

[JBoss JIRA] (JGRP-1910) MERGE3: Do not lose any members from view during a series of merges
by Bela Ban (JIRA)
[ https://issues.jboss.org/browse/JGRP-1910?page=com.atlassian.jira.plugin.... ]
Bela Ban commented on JGRP-1910:
--------------------------------
Added {{GMS.use_all_views_to_determine_merge_leaders}} (default=true) to define whether to select all view creators as potential merge leaders (true), or to select only view creators which are also the senders of view-ids (false). Default is true, so this is a slight change of behavior.
The change is that now we reduced the chances of parallel merges happening, but also slightly increased the chances of a merge leader not being accessible and merging having to wait until that coord is suspected and excluded.

> When connection between nodes is re-established, MERGE3 should merge the cluster together. This often does not involve a single MergeView but a series of such events. The problematic property of this protocol is that some of those views can lack certain members, though these are reachable.
> This causes problem in Infinispan since the cache cannot be fully rebalanced before another merge arrives, and all owners of certain segment can be gradually removed (and added again) to the view, while this is not detected as partition but crashed nodes -> losing all owners means data loss.
> Removing members from view should be the role of FDx protocols, not MERGEx.

[JBoss JIRA] (WFLY-4413) Network connection leak in asynchronous servlet
by jeremy_lv lv (JIRA)
[ https://issues.jboss.org/browse/WFLY-4413?page=com.atlassian.jira.plugin.... ]
jeremy_lv lv updated WFLY-4413:
-------------------------------
Description:
{panel:title=Phenomenon|borderStyle=dashed|borderColor=#ccc|titleBGColor=#F7D6C1|bgColor=#FFFFCE}
When the connection is suddenly terminated during the period we access the asynchronous servlet application, the connection will be leaked. However, the connection won't be leak when we access the synchronous servlet application.

*Some of the stacktrace are as follows:*

[JBoss JIRA] (WFLY-4413) Network connection leak in asynchronous servlet
by Stuart Douglas (JIRA)
[ https://issues.jboss.org/browse/WFLY-4413?page=com.atlassian.jira.plugin.... ]
Stuart Douglas commented on WFLY-4413:
--------------------------------------
I just tried this out and the connection hangs around for 30s until the default async timeout is hit, then it goes away as expected. I tested against both 8.2.0.Final and the most recent upstream and the behaviour was the same.
The behaviour is basically the expected behaviour, because nothing catches the IOException thrown on flush the request basically hangs around doing nothing until the async timeout is hit. I could potentially forcibly kill the underling connection if a write fails, but either way the request object will be hanging around until the timeout.

When the connection is suddenly terminated during the period we access the asynchronous servlet application, the connection will be leaked. However, the connection won't be leak when we access the synchronous servlet application.

Hi, [~swd847]:
I have confirmed the last test code can only be reproduced when the browser is IE and couldn't be reproduced in the other browsers such as firefox and chrome.
Now I have modified some of the code to make sure it can be reproduced both in firefox and chrome. could you please try to reproduced this phenomenon again? I'm sure the phenomenon about the connection leak can be reproduced in your laptop.
Thanks.
