Summary:
There is a race in SstFileManagerImpl between the ClearError() function
and CancelErrorRecovery(). The race can cause ClearError() to deref the
file system pointer after it has been freed. This is likely to occur
during process shutdown, when the order of destruction of the
DB/Env/FileSystem and SstFileManagerImpl is not deterministic.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/9435
Test Plan:
Reproduce the crash in a TSAN build by introducing sleeps in the code, and verify with
the fix.
