> Edit Paging Flow Control defaults to avoid OME on out of box broker
> -------------------------------------------------------------------
>
> Key: ARTEMIS-3943
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3943
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.24.0
> Reporter: Anton Roskvist
> Assignee: Clebert Suconic
> Priority: Major
> Fix For: 2.25.0
>
>
> Starting with version 2.24.0 of the broker, a single client can cause the broker to OOM and terminate if an address is paging and holds enough messages to collectively fill the broker heap.
> To reproduce:
> {code:java}
> $ apache-artemis-2.24.0/bin/artemis create broker
> $ broker/bin/artemis-service start
> $ broker/bin/artemis producer \
> --destination TEST \
> --text-size 100000 \
> --message-count 100000{code}
> Optional:
> Tweak "message-count" + "text-size" above together with the "-Xmx"-property in artemis.profile to be able to trigger it faster
> Kill broker with:
> {code:java}
> $ broker/bin/artemis consumer \
> --destination TEST \
> --message-count 1 \
> --url "(tcp://localhost:61616)?consumerWindowSize=-1" \
> --sleep 60000{code}
> Not saying this is demonstrating proper usage of the client, but this was the easiest way I could think of to reproduce the problem.
> Running the same procedure against an older version of the broker results in no such issue
