Paul,

I've not heard of something that would cause SSL, specifically, to temporarily stop working.

The "Read timed out" message seems to imply that the network itself stopped responding. Hiccups like that do happen... if that happened during an SSL handshake, it could certainly foul things up. The timeout period in an SSL handshake is not a fixed number. Whomever wrote the code that calls the GSKit APIs can change the timeout value. You should discuss this with whomever is providing you with this software. (If this is software that you have written internally, let me know and I'll see if I can find the appropriate details -- but I get the impression that you didn't write this yourself.)

The error messages that say "Peer not recognized" usually occur due to someone attempting to connect to an SSL server with a plain text (or otherwise non-SSL) client. At least, that has been the most common cause in my experience.

What can cause an app using SSL to fail briefly for short window, 2 minutes?
We see SSL failure message in both the iSeries app log and the remote server log.

Remote server log

If an SSL handshake doesn't compete in x amount of time, could this be the cause of the issue?
How long is X?
2 minutes?

Where or how would one start to try and troubleshoot this issue?

Thank You
