Hi, when I use jmeter make perfomance test for doris mcp server 0.6.0, I
found two issues.
1. When use 2 thread or more thread and 1 worker make test in the same
session, the test can't end normally, but have no any error. For example, when
I test for 5 minutes, it will hang on a little over 4 minutes. But in the old
version 0.2.0, it have no the probelem, and in version 0.5.1, it also have the
problem. When I use multi-workes and multi-thread in 0.6.0, it also ok. I
doubt it maybe caused by the session，the same session will share the
connection, wheather it caused by some lock. In multi-workers mode, they are
stateless architecture, so have no effect.
2. When use multi-worker mode for test, it seems run normally, but evrytime
the call of exec_query tool will raise error, as follows:
```
