[GitHub] [incubator-doris] xinyiZzz opened a new issue #6555: [Bug] sendFragment timeout, after high concurrency stress test
xinyiZzz opened a new issue #6555:
URL: https://github.com/apache/incubator-doris/issues/6555
### Search before asking
- [X] I had searched in the [issues](https://github.com/apache/incubator-doris/issues?q=is%3Aissue) and found no similar issues.
### Version
0.14.12
### What's Wrong?
Start 4 jmeter processes, each jmeter process has 200 threads, and an error sendFragment timeout is reported after a period of stress testing.
After closing all jmeter processes and starting a jmeter process and there is only one thread, the sendFragment timeout error is still reported.
It is suspected that the client somewhere is not released:
