ASF GitHub Bot commented on ARTEMIS-1025: ----------------------------------------- Github user franz1981 commented on the issue: https://github.com/apache/activemq-artemis/pull/1119 @clebertsuconic it uses an await with timeout on the write and flush promise offered by the netty channel; it has to return by (Netty) contract either in 2 cases: - timeout occurs (by default io.netty.backpressure.millis=1000 milliseconds) - the data are flushed If it doesn't return we could have some issue on the thread pool used by Netty to perform the flush (the I/O threads), but is pretty strange! Anyway I need feedback mate, I'll ping you ASAP :+1: > OutOfDirectMemoryError raised from Netty > ---------------------------------------- > > Key: ARTEMIS-1025 > URL: https://issues.apache.org/jira/browse/ARTEMIS-1025 > Project: ActiveMQ Artemis > Issue Type: Bug > Components: Broker > Reporter: Francesco Nigro > Assignee: Francesco Nigro > > If you send and receive a lot of messages in short time to Artemis via Netty > connector, the OutOfDirectMemoryError exception is thrown from the client. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
