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...
