# 20162: A conflicting resource update is in progress

Log Type: APPLICATION

Log Level: ERROR

## Description

The requested resource is already being updated simultaneously by another API request. The last request will be rejected to avoid inconsistent state.

### Possible causes

The same API resource is being updated by multiple simultaneous API requests from different threads in a conflicting fashion.

### Possible solutions

* Implement an operation retrier and repeat the failed API requests after an interval of time using, exponential backoff algorithm.
* Serialize your API requests that modify the same resources, and wait until the original request completes and returns an API response, before sending any successive modifications.
