Error description
When issuing a 'DELETE FILESPACE' command for a filespace that contains data in a deduplicaion storage pool and includes a high number of very large files, the TSM server may exhibit a high amount of memory utilization. Under these conditions, the 'DELETE FILESPACE' process performance is severely degraded as well potential memory paging issues that could cause further issues. This is caused by areas of the dedupe processing that make calls for an in-memory list that is built during deletion processing. At end transaction this list is added to a table that is then subsequently deleted by other backend server threads. The current group size used for transaction in this processing can become prohibitive under the conditions. . Tivoli Storage Manager Versions Affected: TSM Server 6.1 6.2 . Customer/L2 Diagnostics (If Applicable) . Initial Impact: Medium . Additional Keywords: performance slow crash exhaustion hang memory paging delete fi del
