> In AS6 run.sh script included an option to raise the limit of open file descriptors. In AS7, where run.sh was replaced by standalone.sh/domain.sh, MAX_FD variable still exists, but it's not used.
> If you decide to include this functionality in AS7, it would be great if the flow of the script would be changed, so it doesn't immediately stop when MAX_FD could not be set, but it tries with a lower value. Something like:
> {noformat}
> STEP_VALUE=50
> i=${MAX_FD}
> while [ ${i} -gt 0 ]; do
>     if ulimit -n ${i} 2> /dev/null 1>&2; then
>         percent=`expr ${i} \* 100 \/ ${MAX_FD}`
>         echo "Open files limit set to ${i} (${percent}% value of desired ${MAX_FD})."
>         exit 0
>     else
>         i=`expr ${i} - ${STEP_VALUE}`
>     fi
> done
> {noformat}
