>From the Solaris 2 FAQ, http://www.wins.uva.nl/pub/solaris/solaris2.html:
Solaris 2.x supports a virtually unlimited number of open
filedescriptors [...].
3.43) How can I increase the number of file descriptors per process?
In 2.3 in earlier this requires poking the kernel. In Solaris 2.4+, this
can be accomplished by adding the following lines to /etc/system:
* set hard limit on file descriptors
set rlim_fd_max = 4096
* set soft limit on file descriptors
set rlim_fd_cur = 1024
Raising the soft limit past 256 may confuse certain applications,
especially BCP applications. Raising the limit past 1024 may confuse
applications that use select().
Programs using stdio or even library calls that use stdio may break when
they have more than 256 files open as that is the stdio limit. Programs
using many filedescriptors should try and reserve a number of low
numbered file descriptors for use by stdio.
HTH.
