Summary

Stress topic workload LeakSanitizer / exit code 100 (release-asan) on the 26.2 line.

Split out from #46517: for 26.2 we track this in a separate issue. The same root cause was fixed on main / stable-26-3 / stable-26-3-1 (LOGBROKER-10550, #46748 / backports #46896, #46897); the fix is not yet on stable-26-2-1 / 26.2.1.7.iamprovider.1.

Related: #46517, umbrella #45120. Backport in progress: #47779.

Environment

  • Branch: 26.2.1.7.iamprovider.1
  • Build: release-asan

Reports

Affected tests

  • ydb/tests/stress/topic/tests/test_workload_topic.py.TestYdbTopicWorkload.test (release-asan, try_1)

Matched by: "LeakSanitizer: memory leaks in NYdb::NTopic read session (TDataDecompressionInfo, StreamReadMessage_ReadResponse parse); see also umbrella issue #45120".
