[AG-TECH] AG connection problems (AGServicemanager)

Hi Alex,
 
We also have run into this issue; however, I can't seem to reproduce it
consistantly enough to file a bug report.  It _appears_ as though it happens
after running grid-proxy-init on the linux side after the certificate has
expired.  I'll try to confirm that so that we can file a report....  FYI, we
are also running RH7.3 on our capture box, so I'm unsure if this is 7.3
specific.

	hi everyone
	
	I'm a computer science master at the university of switzerland in
zurich and
	I'm setting up a test environment with two AG nodes. I have the
systems up
	and running, I did a standard
	+installation of RH7.3 with all updates as of today (Mon Aug  4
09:42:15
	CEST 2003) and I installed the AGTK 2.0 from the main AG site.
	
	got a certificate, created grid-proxies and all on all the machines,
and
	started AGServiceManager.py on all of them (1 audio, 1 video, 1
display). now my
	problem:
	
	when I run the AGNodeService.py and the NodeManagement.py on either
windows
	or linux, and try to connect the audio and video machines, I
sometimes get an
	error:
	
	Exception: Service Manager is unreachable
	https://audio1:12000/ServiceManager
	
	but it's not on all machines, and it's not all the time. I don't know
what
	it is... can somebody help me with this ?
	for instance, I can connect to the audio machine, but the video
machine is
	unreachable, and the other way around.
	
	
	see the log of the agsm below
	
	thank you for your time and effort
	I really appreciate it
	
	alex
