Clebert Suconic commented on ARTEMIS-3272:
------------------------------------------
can you format the thread dump generated a little better? I'm having a hard
time understanding this huge file.
There's probably a better output you can paste here.
The change was to close on demand. I need to check what was causing the close
to happen. Can you send it please?
> Remaining AIO issue from ARTEMIS-3084
> -------------------------------------

> Key: ARTEMIS-3272
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3272
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.16.0, 2.17.0
> Reporter: Anton Roskvist
> Priority: Major
> Attachments: stack

> Hi,
> Starting with artemis-2.16.0 I was getting these WARN messages, followed by a
> broker shutdown:
> {quote}
> WARN [org.apache.activemq.artemis.core.server] AMQ222010: Critical IO Error,
> shutting down the server.
> file=AIOSequentialFile:/path/to/artemis-2.16.0/data/journal/activemq-data-2665706.amq,
> message=Timeout on close: java.io.IOException: Timeout on close
> {quote}
> They were not that frequent, maybe once per week or so. I read that this was
> a known issue that was supposed to be resolved in artemis-2.17.0.
> After upgrading I see this WARN message instead, followed by a thread dump:
> {quote}WARN [org.apache.activemq.artemis.journal] File activemq-data-49.amq
> still has pending IO before closing it
> {quote}
> This does not appear to cause any issues as far as I can tell but it is
> printed several times a day so the log is completely cluttered (from the
> thread dump).
> I am attaching one of the thread dumps from my logs here: [^stack]
> In this setup I am running a static broker cluster of 5 brokers, each
> processing messages at about 40-50 Mbps
> Clients are primarily using OpenWire
> ext4 is used as the filesystem
> Br,
> Anton
