TLS/SSL issue

Just recently I was asking about the use of the SBMJOB equivalent of an IBM
I API to submit a job. I have an answer for that.

Let me tell you what my problem is right now.

I've got two IBM i partitions, say SystemA and SystemB. I establish a
TLS/SSL communications connection between them. Then I can exchange
arbitrary and totally customized messages that only the two endpoints
understand.

SystemA is the client and SystemB is the server. SystemA sends a message
to SystemB with some sensitive PCI-DSS compliant information in order to,
in turn, connect to a third party web service provider outside the
organization. Let's call the latter the Card Processor.

This is done by SystemB calling (literally with a CALL operation) the Card
processor to consume the web service. This program also establishes its
own TLS/SSL connection with the card processor.

It happens that, if the connection with the Card processor is successful,
when it gives control back to its caller, everything works satisfactorily.

But, if the Card processor does not respond within a timeout value, it
throws an exception. The caller to the web service consumer, monitors this
exception and then when it wants to report this result to SystemA, it finds
that the original TLS/SSL connection that was established with SystemA
before, has ended, and it has nothing else to do that to end the job. The
server-side job goes down and then the client goes down too.

This behavior has been observed only if, and only if, the third-party web
service consumer throws an exception to report the timeout. Otherwise it
returns normal and nothing bad happens.

So I would ask these items:

1. On the server side, when I first call gsk_environment_open(), I get a
handle for that.
2. If the third-party (on the same job) calls gsk_environment_open() too,
would it get the same handle as the first one? I mean like if it shares
the same handle?

3. Why would an exception thrown from the third-party web consumer
close/end my original TLS/SSL environment?

4. Would it have to do with Activation Group related stuff?

Well, this is my issue. I have not been able to find out the cause of it.

Will appreciate your comments, tips, recommendations, etc.
