IBM SDS v6.4 and SDI v7.2 on AIX - GLPSSL019E GLPSRV004I

A couple of days ago, I've found this errors on  ibmslapd.log:

2016-03-30T19:46:22.915680-3:00 GLPSSL019E The SSL layer has reported an unidentified internal error, SSL extended error code:4.
2016-03-30T19:46:22.915742-3:00 GLPSRV004I Terminating server.

SSL extended error code:4 means:  "Main memory is insufficient to perform the operation" (See link)


After searcvhing a lot, I've found that the error is due to an incorrect setting of ulimit rss parameter (It was set to default for root, which is the user I use to run SDS).

Then I've changed ulimit as follow:
   

#>grep -p root /etc/security/limits
root:
        fsize = -1
        core = 2097151
        cpu = -1
        data = -1
        nofiles = 4000
        rss = -1
        stack = -1

Relogin, chequed ulimit with "ulimit -a", and restarted SDS: The error was gone...
