Valeriy Ak created ARTEMIS-5100:
-----------------------------------
Summary: Cannot initialize queue: resource temporarily unavailable
on auto tuning journal
Key: ARTEMIS-5100
URL: https://issues.apache.org/jira/browse/ARTEMIS-5100
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.35.0, 2.33.0
Reporter: Valeriy Ak
When the broker starts in the cloud, it runs the {{docker-run.sh}} script.
This script performs auto-tuning for the journal (to achieve the best
performance).
However, the auto-tuning does not read {{broker.xml}} as I expected. Instead,
it tries to determine the parameters for {{SyncCalculation.syncTest}} by itself.
It retrieves the default value for {{maxio}} from
{{{}ActiveMQDefaultConfiguration.getDefaultJournalMaxIoAio(){}}}, which cannot
be changed through configuration parameters or any other way (the value is
4096).
Thus, when {{newContext}} is called and it invokes the native
{{{}io_queue_init{}}}, we encounter an error, and the execution stops.

sync calculation, using default values{code}
I think it happened because the max-io value in the guest OS might be lower
than the default value in Artemis.
