SSLEOFError

[Akilesh K]

Hi,

While running a test case for a multi threaded application I get the below error. As can be seen the test starts and sends a few messages from different threads and then crashes after a while. Each of  my thread uses its own connection and channel.

What does this error mean and how do I get it fixed? I am using pika==1.2.0.

This seems the SSL connection issue. You may try to use the correct SSL client library.

Thanks

Somehow I doubt its related to SSL . It only happens when there are more than one thread and also the first few messages are published perfectly well.

as a thread on stackoverflow says:

There are threading issues with Pika, but as long as you create one connection per thread it shouldn't be a problem.
