Public bug reported:

I have an apcupsd setup in client/server mode for a couple computers.
The "server" computer has the "NETSERVER" config directive enabled. The
client computers are configured with UPS type "net" to connect to the
server computer to get the UPS status. After the acpupsd process has
been running for a while on the server, I get the following errors in
the log:

Jun  8 14:22:02 server apcupsd[1949]: warning: cannot open /etc/hosts.allow: 
Too many open files
Jun  8 14:22:02 server apcupsd[1949]: warning: cannot open /etc/hosts.deny: Too 
many open files
Jun  8 14:22:02 server apcupsd[1949]: Connection from 10.0.0.230 refused by 
tcp_wrappers.

My guess is that there is a file descriptor leak in the code that
protects the NETSERVER incoming connections. This is on Ubuntu 12.04.4.
