[ckan-dev] SOLR or PostgreSQL not coming up after update of CentOS

[Stephan Schrade]

Hi experts,
after updating my CentOS after a couple of weeks my CKAN on this machine 
does not work any more :-(
The website is running but I don't get any connection to the database.

The httpd error log says:

[Wed Jul 22 14:36:57 2015] [error] 2015-07-22 14:36:57,431 INFO

When I try to access solr via web interface (on port 8080) I get a valid 
html page and the log in catalina.out says:

Jul 21, 2015 3:33:48 PM org.apache.coyote.http11.Http11Protocol start
INFO: Starting Coyote HTTP/1.1 on http-8080

Jul 21, 2015 3:33:49 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 5717 ms

How can this happen?
What can I do to find out what is going wrong?

I'm running CKAN 2.2 on a CentOS 6.6 machine.

TIA Stephan
