Frequently Asked Questions
Q: Why is virtual memory usage high?
Consul makes use of LMDB internally for various data storage purposes. LMDB relies on using memory-mapping, a technique in which a sparse file is represented as a contiguous range of memory. Consul configures high limits for these file sizes, and as a result relies on a large chunks of virtual memory to be allocated. However, in practice the limits are much larger than any realistic deployment of Consul would ever use, and the resident memory or physical memory used is much lower.
