[FB3] Memory Leaks. FB does not release memory after load tests.
----------------------------------------------------------------
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.
