perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Pedro,

I am guessing there is something wrong with your postgresql instance. Both esmond and pscheduler use postgresql and pscheduler is also throwing an error: https://152.84.102.250/pscheduler/tasks.

You can try a couple things:

1. Try restarting postgresql-9.5: /etc/init.d/postgresql-9.5 restart

2. Look in /var/log/esmond/django.log for more detailed errors. 

3. Make sure the file /var/lib/pgsql/9.5/data/pg_hba.conf is non-empty. If it is empty let me know and I can help you fix (this is a bug we’ve ran into before)

Thanks,

Andy

Marian,

I did what you suggested (rebooting the node and restarting httppd servers), but same result as attached (Connection refused: proxy: HTTP: attempt to connect to [::1]:11413).

Other suggestions?

Regards,
Pedro Diniz

Hi Pedro,
I suggest to reboot the node to start with, assuming this is SL6/centos6 installation and since there are some proxy errors I suggest to restart both httpd servers as well:
service httpd restart
service httpd24-httpd restart

Once done, please re-check the httpd error log (both /var/log/httpd/error_log and /var/log/httpd24/error_log) if there are still errors afterwards. Let me know if that helped.

Thanks,
Marian
