module_name detected a data space overflow error. One or more samples might be lost.
The data write was unable to write one or more sample records to the sample data space. The data space was in the process of being expanded while the sample records were being added to the data space. These records were dropped to avoid overflowing the data space. module_name represents the module that detected this condition.
None. Sampling continues, but the user might possibly notice sampling errors in some of the reports only if this message appeared continuously throughout the sampling session.
