Summary: Logging storm on server node failure/disconnect during loading through a DataStreamers Key: IGNITE-17944 URL: https://issues.apache.org/jira/browse/IGNITE-17944 Project: Ignite Issue Type: Bug Reporter: Roman Puchkovskiy This can be reproduced in RebalanceIteratorLargeEntriesOOMTest when changing #additionalRemoteJvmArgs() to return this: return Arrays.asList("-Xmx128m", "-Xms128m", "-XX:+HeapDumpOnOutOfMemoryError", "-XX:+CrashOnOutOfMemoryError"); On my machine, when the remote node crashes, the machine becomes barely responsive because all the cores peak to 100% of load. There happens a LOT of logging at that phase, probably a lot of Buffers of DataStreamers get cancelled, so a lot of futures get cancelled, which is made via completing with an exception, which causes a lot of logging. It seems that same thing might happen in production if a node suddently crashes amidst data loading by a client. -- This message was sent by Atlassian Jira (v8.20.10#820010)
