First of all thank you very much
The program is written in java
I used 10 threads to execute the jedis.lpush method in while, and for 2 days all threads were runable and blocked on jedis.lpush.
It seems that none of the timeout methods set by jedis are effective. I hope you can get help, thank you very much
Here’s some of the information I printed in jstack:
