A strange blocking problem when reconnecting an existing dB.

[Ghost]

When my program safely exits after running for some time, it calls“ db.stop ”Class. Then when you run the same program again, 100% of them will be blocked when connecting to the database. It will be blocked for a long time, and finally you have to delete the entire database directory to recover.

connected code below:

func NewDefaultRocksNormalDb(dataDir string) (*gorocksdb.DB, error) {
	rateLimiter := defaultRateLimiter()
	opts := gorocksdb.NewDefaultOptions()
	opts.SetRateLimiter(rateLimiter)
	opts.SetCreateIfMissing(true)
	db, err := gorocksdb.OpenDb(opts, dataDir)  // break point tells me, it will block here
	if err != nil {
		return nil, fmt.Errorf("NewDefaultRocksNormalDb failed: (%s)", err.Error())
	}
	return db, nil
}

key words:

1. After a long run, stop the program;
2. run again
