Hello, guys.
Everything is in subject. I'm experiencing this problem on both my openvz
hosts. For httpd it happens from time to time, for nrpe - always...
Tell please where should I look.
In /proc/user_beancounters "failcnt" is 0 for all options.

Hi man,
I was used nrpe inside vz containers and on the hn from along time ago
and never see behavior like this. Is there some customizations in your
nrpe service start/stop scripts or something, I think there is the
place too look at why this happens. ... I think this situation is not
openvz related in specific, correct me if im wrong
best regs

Thanks for quick reply.

no, all scripts are default. This happens for httpd too.
I suppose it's openvz related. Seems like some misunderstanding between
host and ve...
Systems are centos 4 and 5, latest kernels from repo.

LIke Gary says, the host system just kills the ct's proceses (may be
in a killall `procesname` style :)))
so the thing that u should take care is the procces's start/stop scripts

Ok, nrpe init script does "killproc nrpe" and its killing all processes
named nrpe, inside containers too. But almost all of init scripts do so.
So modify all of them? Looks not so pretty:)

Agree :) it's not so pretty.. but every process from every container
is a seen process on the host

Ok, I've decided to just leave it as is. It's production systems, service
restarts are not so often.
So only solution for this issue now is to use host system just as host.
Tim,
Migration to Debian will be not so simple.
Yes, I think it's needed to send bug report to CentOS/Redhat packaging. I
surprised that no one has mentioned this before.

It gets mentioned every once in a while, but this is a general problem
with centos init scripts and/or most init scripts in general, they are
mostly written to assume a single instance of the service.
The solution is simply to run as little as possible on the host, and
to fix the scripts for the stuff you need to run. Painful, but
unavoidable. Maybe if you submit a patch to rhel, it could maybe make
it into a release in a couple of years ;)

I've submited the bug to RHEL.
https://bugzilla.redhat.com/show_bug.cgi?id=753834
Yes for now it's only to limit services on the host.
