This can be O/S dependent – some O/S have limits on file descriptors, pipes, etc. I would check that.

Second, broken pipes happen when one side closes when there is still action. In Unix C it is easy to do – if you use a piped open but you only want to get the first line of data so your read from the pipe and close … you get a broken pipe every time. This is harmless if that is what you want. Death if not.

You might check your Oracle code for premature closing as I doubt it is stunnel. Can you trap the error and resume and see if it works? It well could.

Essentially what I am saying is this is not directly a stunnel problem, more likely it is an implementation error. Which could be in the Oracle code as I have had problems with it in the past.

More information on the O/S and the Oracle code would help.

Hello,

I have an encrypted connection through stunnel between client and db server, but in connection I have the following errors:

"IO Error: Broken pipe (Write failed) at oracle.jdbc.driver.T4CPreparedStatement.executeForDescribe(T4CPreparedStatement.java:874)"

Could you help me, please?

Thank you in advance
