我们正在使用 tdspool 并尝试在同一台机器上本地使用 tsql 连接到它。 tdspool 似乎可以很好地打开它的连接并开始监听，但是任何连接到池的客户端都会超时。
池.conf
[global]
min pool conn = 5
max pool conn = 10
max member age = 120
[sampool]
user = [REDACTED]
password = [REDACTED]
database = [REDACTED]
server = [REDACTED]
port = 1313 ;change to a non standard port so we can see the connection details in the debug log
当使用 tsql 连接到 127.0.0.1:1313 时，tdspool 输出只是说“接受连接”，没有别的。 freetds.log 输出以下内容:

最佳答案
软件有问题
我们去了官方邮件列表，逐字询问了这个问题。答案似乎是，不重写当前项目就没有。
Client libraries are used and well tested but pool and server are really not in a good shape.
The current state of tdspool is.... it compiles! I'm not surprised it does not run correctly.
That said it's open source. Any help/suggestion/patch is welcome.
我们花了相当多的时间试图找出我们做错了什么，所以这有点痛苦。虽然我将寻求创建/修改现有的 SQL Server 池，但我对 FreeTDS(一个很棒的项目)附带如此不稳定的池感到失望
