A method and apparatus for buffering data in a multithreaded environment is provided. According to one aspect of the invention, log data is generated in response to a request for accessing a resource. A data management structure that is associated with a plurality of data buffers is identified and a reference value that is associated with the buffer management structure is read. The reference value provides information that identifies a particular data buffer that is likely available for buffering data. Based on the reference value a particular data buffer that is associated with said data management structure is selected for buffering the log data.
