Oracle Database Error ACFS-04002: Buffer Allocation Failure
Description
The ACFS-04002 error indicates that Oracle ACFS (Automatic Storage Management Cluster File System) was unable to allocate a required memory buffer. This typically occurs when the operating system or ACFS itself is under memory pressure, or when configuration limits are reached.
Error Message
unable to allocate a buffer
Known Causes
4 known causesInsufficient System Memory
The server running Oracle ACFS lacks sufficient physical RAM or swap space to satisfy ACFS buffer requests.
ACFS Kernel Driver Configuration
The ACFS kernel driver might be configured with buffer limits that are too low for the current workload, preventing larger allocations.
High System Resource Contention
Other processes or applications on the server are consuming a large amount of memory, leaving insufficient resources for ACFS.
Memory Fragmentation
Even if total memory is available, fragmentation can prevent the allocation of contiguous large buffers required by ACFS.
