Hi everyone,

Since applying ptf 7.3 TR8 on our V7R3, we encounter an issue on a http_url_get command.

The 2 different errors returned in http_error are randomly (sometimes, there is no error) :

Code: -1 - Msg: "CommSSL_read: read:(GSKit) An error occurred during SSL processing that was not"

OR

Code: 404 - Msg: "HTTP/1.1 404 Not Found"

Ciphers are even, on the website and on AS/400.

IBM asked us for a trace. They said it's an EWOULDBLOCK or GSK_WOULD_BLOCK condition that creates the issue after applying 7.3 TR8,

as described in their official note https://www.ibm.com/support/pages/node/6237392

And they say it's not an IOS defect, and that "The client application will need to be modified to handle the GSK_WOULD_BLOCK or EWOULDBLOCK advisory condition to resolve this issue"

Here are the PTF that have been installed and at the same time in the IBM note :

            PTF Group              Level          Status
            SF99730         20128             Installed
            SF99867     4              Installed
            SF99722       24              Installed
            SF99725       17              Installed

            The PTF MF99208 is installed.

I tried to add a 30 seconds timout on the http_url_get command, it did not change nothing.

Do you know about this issue and what can be made to handle the GSK_WOULD_BLOCK or EWOULDBLOCK advisory condition to resolve this issue ?

Thank you in advance for your help, and have a great day everyone!
