## Note about pids_limit
|
||||
|
||||
For heavily mult-threaded workloads like databases, the default of 1024 for pids-limit is too low.
|
||||
This parameter controls not just the number of processes but also the amount of threads
|
||||
(since a thread is technically a process with shared memory). See [cri-o#1921]
|
||||
|
||||
In order to increase the default `pids_limit` for cri-o based deployments you need to set the `crio_pids_limit`
|
||||
for your `k8s_cluster` ansible group or per node depending on the use case.
|
||||
|
||||
```yaml
|
||||
crio_pids_limit: 4096
