## Starting Multiple Instances of a Service and Maximum File Descriptors
To start multiple instances of an OpenIM service, simply add the corresponding port numbers and modify the `start-config.yml` file in the project’s root directory,
then restart the service. For example, to start 2 instances of `openim-rpc-user`:
```yaml
rpc:
@ -61,3 +79,9 @@ Modify `start-config.yml`:
serviceBinaries:
openim-rpc-user: 2
```
To set the maximum number of open file descriptors (typically one per online user):
```
maxFileDescriptors: 10000
```
