Watchdog is fine:

root        9405       1  0 12:27 ?        00:00:08 ruby 
/opt/ovz-web-panel//utils/watchdog/watchdog.rb start
root        9412       1  0 12:27 ?        00:00:02 ruby 
/opt/ovz-web-panel//script/server webrick -e production -p 3000 -b 0
root        9415       1  0 12:27 ?        00:00:13 ruby 
/opt/ovz-web-panel//utils/hw-daemon/hw-daemon.rb start

the restart of watchdog didn't help

Can you provide error details saved in /opt/ovz-web-panel/log/production.log ?

Fixed after rebooting physical host. 
I started Web Panel manually and issue gone.

Me too.

I have two almost similar boxes (debian.5, AMD x6, same mem, etc.). And one box 
affected this problem - another is not.

I using owp since 1.7 and just ignore this problem until today. Now upgraded to 
2.0 and problem still here.

One difference - affected box _is_ running ruby services in VE, another is not. 
One more - it`s look like you can live longer after restart if you don`t try to 
manipulate - just looking. 
If change any VE then fall is near.

I played above an hour with 2.0 - all in attached log.

same problem with OpenVZ Web Panel 2.0

Internal error: undefined method `pluralize' for #<Object:0xb680af3c>
Rendering /opt/ovz-web-panel/public/500.html (500 Internal Server Error)

restarting of OVZ-web-panel fixes but not for a long time

Confirmed on Debian squeeze, using ovz-web-panel 2.0. It recently began 
behaving as described, I can however not pinpoint the time to something 
particular changed in the system or openvz setup.

Restarting watchdog DID help! Although only for a couple more requests. 
Restarting watchdog again would continue resolve the issue temporarily. 

Attaching log entries from the erroneous request.

Also, consider moving the project to another host. Perhaps one that does not 
require you to use a Google Account just to report/comment on bus... ;-)

Got it!

In short - server fail, probably, when try to render zero value in server free 
disk space bar.

To reproduce on 2.0
1. Take good working server, without any zero percents in df output
2. Mount iso image via loop device
3. Sync server via web

Result.
Server fail with Internal error: undefined method `pluralize' for 
#<Object:0x7fb481bba5c0>

More digging.
First of all i look in the code of helper to look in pluralize invocation
vendor/rails/actionpack/lib/action_view/helpers/number_helper.rb

####
def number_to_human_size(number, *args)
 return number.nil? ? nil : pluralize(number.to_i, "Byte") if number.to_i < 1024
####

I dig in ruby for 2 hours but still have no complete understand of this code. 
(It is my first look in ruby :) )

So i look in code that call this helper
app/controllers/admin/hardware_servers_controller.rb

#####

                :free =>  partition['free_bytes'],
                :used => partition['used_bytes'],
                :total => partition['total_bytes']
#                :free =>  helper.number_to_human_size(partition['free_bytes'], 
:locale => :en),
#                :used => helper.number_to_human_size(partition['used_bytes'], 
:locale => :en),
#                :total => 
helper.number_to_human_size(partition['total_bytes'], :locale => :en)
###

I just tell that i agreed to get raw values instead of humanized and it is 
solve the problem - not failing any more.

Later i connect host with patched code to another host that work stable and so 
- used original code.
After sync  - stable server fail - and at this point a start to think that 
problem in data - not in code. 

At this point i was really close to think about zero values. I mount loop 
device and reproduce bug.

Hope it help someone - good luck!
