Not sure if this will add to the same thread or create a new one so just 
to recap.

On one of our backuppc servers the Web GUI has been failing to launch 
with a 504 Gateway timeout error showing up.

One responder asked if backuppc service was running which I checked with

pgrep backuppc

this showed nothing initially but then realised the process is listed as 
BackupPC not all lower case.

On trying service backuppc restart I get this response

:~$ sudo service backuppc restart
  * Restarting 
backuppc...                                                       No 
process in pidfile '/var/run/backuppc/BackupPC.pid' found running; none 
killed.

If I then run pgrep BackupPC the number of pids has incremented by 1....

Running ps -ef | grep BackupPC shows these pids are all as follows:

backuppc 20340     1  0 14:58 ?        00:00:00 /usr/bin/perl 
/usr/share/backuppc/bin/BackupPC -d

Just to test things I tried killing all the running BackupPC PIDs and 
when all done I could then access the web interface but got error:

Error: Unable to connect to BackupPC Server
This CGI Script (/backuppc/index.cgi) is unable to connect to the 
BackupPC server on <myservername> port -1.
Perhaps the BackupPC server is not running or there is a configuration 
error. Please report this to your Sys Admin.

On running service backuppc start I can no longer connect to the web GUI 
at all.

This is all on Ubuntu 12.04 server identical in every other way to 2 
other working BackupPC Servers in production.

Only change of any note was to remove a host which no longer needs 
backed up from both /etc/backuppc/hosts, the config file for that host 
from /etc/backuppc and from /var/lib/backuppc/pc/.

I've compared settings between the problem server and 2 working ones and 
can see no differnence between them in either config file content or the 
permissions on those files. At a loss as to how apparently running the 
backuppc service blocks access to the web interface.

I've been googling this issue for a few days now and come up with nada 
so anyone else out there with suggestions is welcome to chime in.


cheers.
