Gyula Fora created FLINK-4193: --------------------------------- Summary: Task manager JVM crashes while deploying cancelling jobs Key: FLINK-4193 URL: https://issues.apache.org/jira/browse/FLINK-4193 Project: Flink Issue Type: Bug Components: Streaming, TaskManager Reporter: Gyula Fora Priority: Critical
We have observed several TM crashes while deploying larger stateful streaming jobs that use the RocksDB state backend. As the JVMs crash the logs don't show anything but I have uploaded all the info I have got from the standard output. This indicates some GC and possibly some RocksDB issues underneath but we could not really figure out much more. GC segfault https://gist.github.com/gyfora/9e56d4a0d4fc285a8d838e1b281ae125 Other crashes (maybe rocks related) https://gist.github.com/gyfora/525c67c747873f0ff2ff2ed1682efefa https://gist.github.com/gyfora/b93611fde87b1f2516eeaf6bfbe8d818 The third link shows 2 issues that happened in parallel... -- This message was sent by Atlassian JIRA (v6.3.4#6332)
