All `csf` commands hang

[serverserve]

All csf commands on this server appear to hang, for example:

`csf -r`
`csf -g $IP`
`csf -x`

A strace doesn't show anything useful:

```
[root@srv csf]# ps aux | grep csf
root 2234908 8.2 0.0 169596 21016 pts/2 S+ 11:34 0:00 /usr/local/cpanel/3rdparty/bin/perl /usr/sbin/csf -v
root 2234932 0.0 0.0 114760 968 pts/0 S+ 11:34 0:00 grep --color=auto csf
[root@srv csf]# strace -p 2234908
strace: Process 2234908 attached
read(6,
```

Any ideas?

This is now resolved - Looks like an RPM issue, upcp update resolved it.
