Fix several memory leaks in the presence server (!319) · Merge requests · BC / public / flexisip · GitLab

Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.
