hi atin,

here is my current setup:
$ ulimit -n -H
65536
$ ulimit -n
256

so my hard limit is 65536 and current limit in shell is 256. are you
saying 256*67% (poll array created by helix) exceeds the OPEN_MAX and
causes those errors? shall I set it to a smaller number?   My
/usr/include/limits.h seems to define OPEN_MAX as 256, so 67% should
never exceed. I am confused.
