SSL Session Data Length Error

 11 April 2016 09:40:42
After upgrading your Domino Server to 9.0.1 FP5 IF1 you may notice more or less often an error on the console:

New SSL session data length of 103 bytes is larger than the
current size of 100 bytes.


IBM published an APAR Request about this issue a few days ago:

Error description
                Since 9.0.1Fp5IF1, the defaults SSL SESSION SIZE is causing the
                following warning to be thrown more often.
               
                   New SSL session data length of 103 bytes is larger than the
                current size of 100 bytes.
               
                Default size may be to small for generall SSL and is causing
                the warning
                

Local fix
                Set SSL_SESSION_SIZE ini to a high value hence extending the
                default


To get rid of this messages set SSL_SESSION_SIZE in your notes.ini to 1024 bytes for example:

SSL_SESSION_SIZE=1024
