No suggestion, only to confirm that I see the exact same issue on

SunOS xxxx.xx.xx.xx 5.10 Generic_118855-19 i86pc i386 i86pc

which is an amd64 box, and OTP was built in 64-bit mode.

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.
