>Description:
Because rup and rusers did not close RPC handle after
clnt_call(), they may exhaust file handles if many hosts
were specified by command line arguments.
>How-To-Repeat:
On csh,
% limit openfiles 16
% rup host1 host2 host3 ...
host1 12:59pm up 31 days, 13:50, load average: 0.02 0.06 0.07
host2 12:59pm up 31 days, 13:50, load average: 0.02 0.06 0.07
...
rup: unknown host "host15"
...
This behavior may depend on your environment such as
/etc/host.conf.
>Fix:
Simply do clnt_destroy() like this.
