| ## How do I increase the memory map area limit? | ||
|
|
||
| Memgraph allocates many small memory mappings, and on larger graphs the default Linux limit (`vm.max_map_count = 65530`) can be hit. This typically surfaces as a hung transaction, `munmap` errors, or `bad_alloc` crashes. Memgraph recommends roughly one memory map area per 128 KB of system RAM. The full table and background are in the [system configuration docs](https://memgraph.com/docs/database-management/system-configuration#increasing-memory-map-areas). |

Our guidance on this actually changed recently to 1 per 64 kb

| For an 8–32 GB host, `262144` is the recommended starting value. Set it for the current session: | ||
|
|
||
| ```bash { target="ubuntu:latest" } | ||
| sudo sysctl -w vm.max_map_count=262144 | ||
| ``` | ||
|
|
||
| To persist the change across reboots, add it to `/etc/sysctl.conf` or a drop-in under `/etc/sysctl.d/`, then reload: | ||
|
|
||
| ```bash { target="ubuntu:latest" } | ||
| echo 'vm.max_map_count=262144' | sudo tee -a /etc/sysctl.conf | ||
| sudo sysctl -p |
