Aha! :-) Dollars to doughnuts Solaris's "mkdir" system call is setting
errno to EMFILE when it fails.
Anyone care to verify this? Bad Solaris, bad! Your man pages lie! :-)
Version 2.32-BETA-1 will not directly fix this. However, there is a
kernel setting to increase the number of open files in Solaris. By
default, this is 256, but you can bump it as high as 1024 with
"ulimit":
ulimit -n 1024
You can increase the hard limit by putting:
set rlim_fd_max=8192
in /etc/system and rebooting. (This is on Solaris 9 and untested...)
