root@solaris:~# ulimit -n
256Since a a few SRU this limit has now a different default.
root@solaris:~# uname -a
SunOS solaris 5.11 11.4.30.88.3 i86pc i386 i86pc

4095
root@solaris:~# ulimit -aJust in case you are wondering why some stuff suddenly works without further administrative intervention.
The system-wide limit was changed as well, it is now calculated based on the memory the system has.
