Clebert Suconic commented on ARTEMIS-3943: ------------------------------------------ [~AntonRoskvist] I will rename your JIRA here to tweak defaults on page-flow-control and max-read messages....since this discussion lead me to make these changes. it would be nice to keep the discussion here referenced on the change I am making. > Clients can cause broker OOM when reading paged messages > -------------------------------------------------------- > > 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 > Priority: Major > > 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 -- This message was sent by Atlassian Jira (v8.20.10#820010)
