[Xymon] df hanging will cause xymon-client to hang.

[Cédric BRINER]

Hello,

I'm running a xymon-client on a Debian Jessie.

OS: Debian
OS-Release: 8 (Jessie)
xymon-client version : 4.3.17

The error happend due to a nfs ressource not responding. I suppose that
as xymon launch "df" to get information and as the nfs was hanging, the
xymon-client is no able to detect that the df hangs and it does not send
any data to the server. Worst, the xymon-client is not verbose at all,
it does not tell this test (df) takes too long to accomplish.

Many thanks for xymon.

Regards.
