Open Microscopy Environment

Dear forum members,

after upgrading omero server and omero.web to 4.3.1, I can no longer use the web interface. It seems that it fails to find some of the components. I can log on and see home page, but when I click on data, apache returns a "Internal Server Error". Configuration was redone following instruction on omero website. omero config get returns

omero.db.name=omero
omero.db.pass=**************
omero.db.user=omero
omero.web.application_host=http://cedre-5a.med.univ-rennes1.fr:80
omero.web.application_server=fastcgi-tcp
omero.web.debug=True

The OMEROweb.log contains no error (see below) but the apache error log contains issues about incomplete header. Apache2.conf is configure with the auto-generated stanza (during omero web configuration). It seems not a generic apache2 / cgi issue since primer3plus running on the same server still works fine. The computer was freshly restarted to update the system after omero upgrade.
Any help would be very welcome.

Thanks a lot in advance

Best regards

Jacques

What's the output of:

show?

Cheers,

Dear Josh,

Thanks for your reply. Here is the output of diagnostics. However, I found nothing suspect in it.

Thank you for your help!

Jacques,

could you attach your var/log/OMEROweb.log in its entirety? There seems to be a lot more going on in there then the snippet here:

Code: Select all

Log files: OMEROweb.log 464.0 KB errors=162 warnings=15


Thanks,
~Josh

Dear Josh,

here it is.

Thanks for your help

Jacques

Josh,

by the way, I tried to run using fastcgi (without tcp) at some point on the 14th of July without success. So it may be that some error in the log I sent are related to that.

Best

Jacques

Hi Jacques,

Could you please stop web by:

Code: Select all

bin/omero web stop

then double check if processes are no longer running by:

Code: Select all

ps uxwf

If you still see something like that:

Code: Select all

please kill them by hand, then start web again by:

Code: Select all

bin/omero web start

if this does not help could you please give us the output of

Code: Select all

ps uxwf | grep runfcgi

Thx
Ola

Hi Ola and Josh,

I still experience the same issue. Here is what I did and at the bottom the command output you asked.

Thanks for your help

In addition to my previous comment please set the config back to fastcgi-tcp. You might also restart apache on the beginning, just in case.
