Hmmm... can you use lsof on the PID of snmpd, and see how many files it has
open? If it isn't release a file descriptor, that's a pretty serious bug. But
it might be an OS limit that has been hit....

Of course, I'm not sure what we should do if we can't read the hosts.allow
file.

You are lost in a twisty maze of little standards, all different.
