Two different threads have reported acquiring a lock with the same key at the same time about redisson HOT 6 CLOSED

Please share the code to reproduce the issue.

Make sure that the lock wasn't unlocked by the time when the second thread acquired it.

Thanks reply,

1. the log shows that the two threads acquired the lock in a very short period of time. I don't think it is the case of releasing and acquiring the lock again.
2. I didn't assigned a leaseTime and unlocked in finally body.

private void generate() {
        RLock lock = redisson.getLock(key);
        try {
            String threadName = Thread.currentThread().getName();
            boolean locked = lock.tryLock();
            if (locked && shouldGenerateTask() {
                log.info("locked by key:{} with thread：{}", key, threadName);
                saveTask();
            }
        } catch (Exception e) {
            Thread.currentThread().interrupt();
        } finally {
            if (lock.isHeldByCurrentThread()) {
                lock.unlock();
            }
        }
    }

This is occurring in a concurrent scenario where the real situation involves listening to a database change data capture (CDC). Then, two threads simultaneously acquire the lock and save two separate task data.

Can you add log.info("unlocked1 by key:{} with thread：{}", key, threadName); after if (lock.isHeldByCurrentThread()) {

add log.info("unlocked2 by key:{} with thread：{}", key, threadName); after lock.unlock();
