[ome-users] Server error (500). Why is this displayed

Hi Simon,

Thanks for your quick response (as normal!) ;-)

I have stopped and restarted OMERO.web, as requested, using "<omero>/bin/omero web stop" and "<omero>/bin/omero web start".  Once I had stopped OMERO.web, all of the "django" processes did stop correctly.  Are there any other processes that I should check as well?

OMERO.web stopped and restarted successfully, but the "/opt/Omero/var/log/OMEROweb.log" log file is STILL not being written to.  There are also no other OMEROweb.log files on the system.

The "Server Error (500)" message that I am seeing includes the following error message:

Traceback (most recent call last):

  File "/opt/OMERO.server-4.4.8p1-ice33-b304/lib/python/django/core/handlers/base.py", line 150, in get_response

Hi John

You're right, I should've said OMEROweb.log. The fact that it's empty is a bit strange though. Is it possible you've got an old OMERO.web running from a previous server upgrade? Could you run `omero web stop`, then verify all relevant processes are killed (you can use something like `ps -ef | grep django` to check). If there are any still present you can try killing them manually, then restart OMERO.web?

If that doesn't work then could you copy and paste the error message from the dialog- if there's no private information it would be helpful if you could CC the ome-users list, so that people don't see a hanging conversation. If we still can't figure out the problem then server credentials could be useful.

Hope this helps,

Simon

Hi Simon,

I'm afraid I am not able to find a log file called  OMERO_web.log!  Where should this be located?

There is a logfile in <omero>/var/log called "OMEROweb.log", but the date on this file is September, and the file is empty!  There is also a file called "OMEROweb_request.log", which the same date which is also empty!

I have looked through the blitz log, but this does not seem to contain any errors or warnings at the time when I see this message.  Would you like me to send you a copy of that?

The server is actually available through our firewall, so I can give you credentials on the server for you to see the error occur, if you would like!

Thanks
John

Hi John

You should be able to login from multiple browsers/locations without errors. Could you send us your OMERO_web.log?

Thanks

Simon

Hi,

I have built a new omero server, but during testing I sometimes see the following "Server Error (500)" screen when I log in.  I am using Omero 4.4.8 with ice 3.3.

I notice that this seems to occur when I access the same user account from different computers or browsers.  Is this because I have not logged out correctly from another sessions?  Is there a way to remove the likelihood of users seeing this screen?

Thanks
John
