Try enlarge kyuubi.frontend.thrift.max.worker.threads, which default value is 999.
BTW, please paste log text instead of picture.

thanks for trying，how many concurrent users and applications do you have? we can increase the thead pool size for both FE and BE of single server instance, and also use more server instances for load balancing to increase the total client concurrency.
