{% hint style="info" %}
Events with priority set as Critical will be retrieved from storage first and sent before Normal events. When the local storage is full, and new events need to be stored, the oldest events with the lowestpriority are deleted first. If the storage is full of logs with Critical priority, then tracking an event with Normal priority will fail asthe SDK can't make room in that case. If you also use the Crashes service, crash logs are set as Critical and share the same storage as events
