Hello
Everyone.
We've been using
Gnokii as part of our monitoring suite here at Manux, in order to send us Text
alerts when a host alert escalates to that level.
2 servers are setup
here with Gnokii - one is a Virtual machine. Both are Debian Sarge (kern
2.4.27).
The Virtual machine
has win2k3 server as it's host. Notably we use Supervise to manage whether the
service is up or down.
We frequently run
into a problem where the Virtualized server will fail to send out Text messages,
and this only comes right after using the Kill command to knock out any
instances of "smsd", including the "svc -d" and "svc -u" commands to get the
service running again. Sometimes text will fail straight away and will need the
process to be repeated then it will come right.
Has anyone had this
kind of problem before?
I am starting to
think there is a virtualization problem with this machine, as the one that is
setup on baremetal _never_ fails. The two cellphones are exactly the same, we've
even swapped them over to test this. I have strace'd gnokii and smsd to try and
pick up on any incompatibilities / crashing code / unmet dependencies etcetera,
but nothing seems to show up as having a problem.
Could this be
the Host Operating System polling the hardware Serial port we are
using, causing a fault with the Virtual Guest ? - how might we test for
this?
Thanks for any
information.
Cheers,
