Ah yes I had a question about that logfile...... on both Bw+Lat it's 
overwritten once an hour by  /etc/cron.d/cron-service_watcher that runs

root /opt/perfsonar_ps/toolkit/scripts/service_watcher &> 
/var/log/perfsonar/service_watcher_error.log

output = 11 identical lines in /var/log/perfsonar/service_watcher_error.log 

Can't exec "runlevel": No such file or directory at 
/opt/perfsonar_ps/toolkit/scripts/../lib/perfSONAR_PS/NPToolkit/Services/Base.pm
 line 147.

I looked that up, the line is
my $runlevel_output = `runlevel`;

Now 
sudo -u perfsonar runlevel
works fine so why should it be unable to find/execute /sbin/runlevel? 
Unless perfsonar acct's PATH gets mucked with & /sbin removed? Or something?

On the Bw box (only) I changed Base.pm:

my $runlevel_output = `/sbin/runlevel`;

So, on the Lat box /var/log/perfsonar/service_watcher_error.log consists 
as before (& as will be forever) of 11 identical lines :

Can't exec "runlevel": No such file or directory at 
/opt/perfsonar_ps/toolkit/scripts/../lib/perfSONAR_PS/NPToolkit/Services/Base.pm
 line 147.

On the Bw box, the error has changed, now 11 identical lines of

Use of uninitialized value $chkconfig_output in split at 
/opt/perfsonar_ps/toolkit/scripts/../lib/perfSONAR_PS/NPToolkit/Services/Base.pm
 line 167.

Hmm that line is 

my $chkconfig_output = `chkconfig --list $self->{INIT_SCRIPT}`;

oooo don't really / really don't want to debug that!......  =:o
