Anton Roskvist commented on ARTEMIS-3272: ----------------------------------------- I have attached the files you requested. I don't really know what happened to the formatting in the original file, but I made these with windows line endings, hope they look better. Yes, I can sort of reproduce it... it happens several times a day in a testing environment. So not on demand, but reliably. > 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: broker.xml, formatted_stack.txt, stack, stack.txt > > > 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.
