[ome-devel] Blitz-0 localhost error / Django errors

Wed Dec 1 12:19:27 GMT 2010

Dear All,
I've just upgraded my OMERO installation to 4.2.1, but it seems something went wrong. Actually, I'm not really able to understand if my installation is working correctly or not.

I can normally start the OMERO admin:

omerouser at isin09 /home/OMERO/OMERO.server-Beta-4.2.1/bin> ./omero admin start

Creating /home/OMERO/OMERO.server-Beta-4.2.1/var/master
Creating /home/OMERO/OMERO.server-Beta-4.2.1/var/registry
No descriptor given. Using etc/grid/default.xml
Waiting on startup. Use CTRL-C to exit

This seem to work fine (no errors on the console), but if I look at the Blitz-0-log I notice some errors:

omerouser at isin09 /home/OMERO/OMERO.server-Beta-4.2.1/var/log> tail -500f Blitz-0.log 

2010-12-01 12:53:30,641 INFO  [                ome.services.blitz.Entry] (      main) Creating OMERO.blitz. Please wait...

What is the meaning of "unable to set localhost"?

In any case, after this error, OMERO seems correctly working:

2010-12-01 12:54:03,748 INFO  [    ome.services.util.ServerVersionCheck] (      main) -------------------------------------------------

I'm able to start the django server:

omerouser at isin09 /home/OMERO/OMERO.server-Beta-4.2.1/bin> ./omero web start

Starting OMERO.web... Validating models...
0 errors found

Django version 1.1.1, using settings 'omeroweb.settings'
Development server is running at http://0.0.0.0:4080/
Quit the server with CONTROL-C.

But, as soon as a client connects, this message is printed on the console:

Can anyone help me?

Thank you very much for your help!
