Hello, 

After upgrading a pS box from 3.3.2 to pS 3.4, its web interface stopped working:
------------------------------------------------------------------------------

http://200.19.119.101/toolkit/

Gateway Time-out
The gateway did not receive a timely response from the upstream server or application.

Can you SSH into the host?  The gateway timeout could be a number of things. That's what happens when apache doesn't respond. Maybe try restarting apache (/sbin/service/httpd restart) or rebooting the host. 

I did restart the http service and also rebooted the host, but the result is the same. 

Maybe there is another process, - i.e.: cassandra - which the web interface depends on?

Now I noticed there are lots of error messages in the http log like this:

/var/log/httpd/error_log:[Tue Oct 07 15:26:34 2014] [error] cassandra_db [DEBUG] Flush called

The shell is likely the more inaccurate of the two. I believe motd (the file that provides the login message) is regenerated after reboot. Did you reboot this host after upgrade?

Yes, I did.

The filtered log without the "cassandra_db Flush called” errors is available at: https://dl.dropboxusercontent.com/u/970090/error_log.txt

The complete log is available at: https://dl.dropboxusercontent.com/u/970090/error_log_full.txt

Thanks,

Alex
