Key: CORE-5416 URL: http://tracker.firebirdsql.org/browse/CORE-5416 Project: Firebird Core Issue Type: Bug Affects Versions: 3.0.2 Environment: FB 3.0.2.32641 SuperServer x64, Win10 x64 Pro, IBProvider Test System Reporter: Kovalenko Dmitry Attachments: fb_image.png, fb_performance.png Firebird does not release memory after completion of load tests. Size of each memory leaks ~ equal to size of page cache One interest moment: 1. When I execute (sequential) two "load tests set" without pause - FB not releases memory after second set. @call run_test_w64_local2_d3.bat @call run_test_w32_local2_d3.bat Memory leak (approximately) == 3.5 GB 2. When I added a pause (10 min) between runs - I see 2xLeaks. @call run_test_w64_local2_d3.bat sleep 10m @call run_test_w32_local2_d3.bat Memory leak (approximately) == 7GB --------------- Database Page: 16KB Changes in firebird.conf: DefaultDbCachePages = 200000 UserManager = Srp, Legacy_UserManager MaxUnflushedWrites = -1 MaxUnflushedWriteTime = -1 WireCrypt = Enabled ---------------- Additional information for attached screenshots - because I executed parallel tests for two databases, memory leaks was multiplied by two and equal (at current moment) to 21GB. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://tracker.firebirdsql.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira ------------------------------------------------------------------------------ Developer Access Program for Intel Xeon Phi Processors Access to Intel Xeon Phi processor-based developer platforms.
