[erlang-questions] R11B-2 on Solaris 10 kpoll problem

It works fine on our Solaris 10 sparc machines (unfortunately we do not 
have any Solaris 10/x86 machines yet) by default, but if I lower max 
open files to 256 (or lower) I get the same problem. I googled a bit on 
this and apparently Solaris 10 doesn't want the size of the result array 
passed in the /dev/poll ioctl to be greater than OPEN_MAX. The size of 
the result array in our case is 256. Hopefully I'll find the time to 
look closer at this before we release r11b-3. Increasing max files to 
something larger than 256 (ulimit -n) will hopefully work as a 
workaround for you.
