             Summary: 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: 2.17.0, 2.16.0
            Reporter: Anton Roskvist
         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
