MSSQL on Linux: SQL Server Out Of Memory

Microsoft.SQLServer.Linux.EventRule.DBEngine.EventCollectionRule.DBEngine.SQLServerOutOfMemory (Rule)

SQL Server has failed to allocate the sufficient amount of memory to run the query.

Knowledge Base article:

Summary

SQL Server has failed to allocate the sufficient amount of memory to run the query.

Causes

The issue may be caused by a variety of reasons including operating system settings, physical memory availability, or memory limits on the current workload. In most cases, the transaction that failed is not the cause of this error. Diagnostic queries, such as DBCC statements, may fail because server the does not have sufficient memory

SQL Server Memory-Optimized Data uses more memory and in different ways than SQL Server does. It is possible that the amount of memory you installed and allocated for Memory-Optimized Data becomes inadequate for your growing needs. If so, you could run out of memory.

Resolutions

See the topic Monitor and Troubleshoot Memory Usage for guidance that can help you avoid many OOM situations.
