While running a query on Dremio 4.6.1 installed on Kubernetes, we are getting the following error message from Dremio UI:
ExecutionSetupException: One or more nodes lost connectivity during query. Identified nodes were [dremio-executor-2.dremio-cluster-pod.dremio.svc.cluster.local:0].
Dremio-env config has the following settings: DREMIO_MAX_DIRECT_MEMORY_SIZE_MB=13384 DREMIO_MAX_HEAP_MEMORY_SIZE_MB is not set We are using workers of 16G /8c (Total of 10 workers) 1 Master Coordinator with the same config Zookeeper with 1G/ 1c
Any idea what's causing this behavior ?
By doing a live logs tail before the worker crashes here are the logs:
An irrecoverable stack overflow has occurred.
Please check if any of your loaded .so files has enabled executable stack (see man page execstack(8))
