René Cordier created JAMES-3997: ----------------------------------- Summary: Netty backpressure for IMAP Fetch Key: JAMES-3997 URL: https://issues.apache.org/jira/browse/JAMES-3997 Project: James Server Issue Type: Improvement Affects Versions: 3.8.0, 3.8.1 Reporter: René Cordier Fix For: 3.9.0
Some OOM IMAP issues on a production environment using James have been detected, regarding the method IMAP FETCH. We seem to do to write out: {code:java} channel.writeAndFlush()Unpooled.wrappedBuffer(buffer)); {code} without any checks. Making the method using intermediate buffers in a slow network, potentially exploding the memory. Need to investigate this issue and enhance this processus, maybe by using Netty backpressure instead? -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: server-dev-unsubscr...@james.apache.org For additional commands, e-mail: server-dev-h...@james.apache.org
