Question about NRPE operation

[schönfeld / in-medias-res]

Hi,

i'm having some problems with checking a ncpfs filesystem and
got a suspicious on my mind, so i have a question about how
the NRPE does operate.

Ok, here we go:
Nagios initiates a check of a particular service on Host X,
so it does send a request to the NRPE daemon on Host X.

Host X checks the request and starts the plugin which can do the
requested service check and switches into wating state => waiting for
the plugin answere.

Now imagine that the ncpfs is busy, because of another "heavy operation"
on it. So the plugin runs and runs, but has to wait for the filesystem
and does not return a result to the nrpe in the meanwhile.

So now the question is: Does the NRPE Server has an timeout after which
it'll *kill* the plugin? If so: Linux ncpfs is not able of threading
ncpfs operations. So if one process is accessing the ncpfs and gets
a SIGKILL, the ncp connection becomes invalid and the source of my
problem would be identified.

Thanks in advance
