perfSONAR User Q&A and Other Discussion

[Daniel Paiva <>]

PS.: Apparently, restarting apache2 service was enough to reestablish the server functionality

Hi Daniel;

We have not had any reports similar to yours.  You can take some measurements of the 'working' system now, and again when you see these problems arise:

 df -h
 free
 ps auxw

Also, you can re-start the services via init instead of rebooting:

 sudo /etc/init.d/apache2 restart
 sudo /etc/init.d/ssh restart

Thanks;

-jason

I am experiencing server shutting down connections from either http or ssh.

When system reboots everything goes back to normal for a short time.
After this time the problem occurs again.

I could not find error messages yet.

Did anyone have such problem?
