Well the problem is: i can't, because the plugin is a script that relies
on reading a specific file which is located on the novell
filesystem. Well - if the problem occurs (with ncpfs) than the command
gets into an infintive wait state, until nrpe sends a SIGKILL. If my
script handles SIGALRM all it can do is do send a KILL signal to the
task which tries to read from the ncpfs and then i would have won
nothing but a broken novell connection.

Anyways: We found a solution. The plugin hangs if novell connection
is busy because of a process which is running constant and reading
from the novell filesystem regulary. We did renice this process and
now we don't have the problem, where the plugin gets into an infitive
wait state. Problem solved.
