It explains how to increase the memory for Java (DbVisualizer). Open Help->Online Resources and choose the FAQ page. Virtual Memory Problem! The application is running low on virtual memory. If there are fewer queries in parallel during the second attempt, the query should succeed.Whenever I save, I got the following error message. The query profile for a query killed on a coordinator node contains the following error: Query canceled - out of memory, check the query profile for detailsĭremio recommends trying the following suggestions, in order, if the heap monitor kills a query: The query profile for a query killed by a heap monitor on an exector node contains the following error: Query was cancelled because it exceeded the memory limits set by the administrator. Any Java system property can be added to this file and each row is interpreted as a standard system property to the Java. (This file is located in the installation directory. On a coordinator node, the heap monitor cancels all queries in the planning phase. If there are fewer queries in parallel during the second attempt, the query should succeed.

Memory and task management: DbVisualizer includes a task manager allowing users to interrupt long-running tasks and receive alerts about high memory usage.

To prevent JVM failures due to a lack of heap memory, Dremio’s heap monitor kills queries if the JVM’s heap utilisation stays above the threshold of 85%, even after a full garbage collection. Note: Dremio requires DREMIO_MAX_MEMORY_SIZE_MB to be at least 4 GB.

Increasing the amount of memory that Dremio is able to consume may solve your problem.įor the DREMIO_MAX_DIRECT_MEMORY_SIZE_MB allocation, be sure to leave at least 1-2 GB of memory for the OS. If you see queries failing on an instance that’s running out of memory,
