Hello Manoj, Diego,
thanks a lot for your replies.
I showed the APAR to one of my colleagues at Networks Team, and he told me that this doesn't apply to us.
At our installation the authentification is done by the server (handshakerole), so as ClientAuth Type we have the default ("Required")
The messages I posted were just an example, they are from different locations yes, sorry for not making that clear.
We have others, similar but with different reason codes, for example, we also have: 77B17343 and 77B77221 RCs.
Thanks!
ClientAuthType
Specifies the type of client certificate validation to be performed for connections in this AT-TLS environment. Client certificates are requested only if HandshakeRole is set to ServerWithClientAuth. Valid values are:
PassThru
Bypasses client certificate validation.
Full
Performs client certificate validation if the client presents a certificate.
Required
Requires the client to present a certificate and performs client certificate validation. This is the default.
SAFCheck
Requires the client to present a certificate, performs client certificate validation and requires the client certificate to have an associated user ID defined to the security product.

Hi,
It looks like the remote client has reset the connection.
If you look at the first message with RETURN CODE: 1121, it seems clear. What I don't find is the reason code
The message after it with RETURN CODE: 1127 which seems to be a long time after the first one is a connection timeout and looks like a complete different IP address. It doesn't look like related events.
That's all we can find with this information. It could be the APAR stated by Manoj.
Hope it helps.
D.

Hello,
what is triggering the DSNL511I messages at the masters?
What is the event that make them appear, sometimes it seems to be every X minutes, following a pattern, but not always.
I would like to review from where does Db2 take these Locations and try to contact them. Or is it something contacting it? Is there a way or a place to know it?
Thanks,
