     3Sometimes our servers will stop responding, experience extremely high loads or do other unpredictable behavior.

     5Our shared servers now have scripts installed to help analyze and record what is going on so you don't have to remember all the right commands.
     6
     7At the moment, these scripts are only installed on our shared servers (malcolm, chavez, mandela, viewsic, etc.).
     8
     9If a shared server experiences unpredictable behavior, please do the following:
     10
     11 * Become root on the machine
     12{{{
     13sudo -i
     14}}}
     15 * Run the analyze-server script
     16{{{
     17analyze-server
     18}}}
     19
     20The analyze server scripts will generate a lot of files that you can read to help determine what the problems is. In addition, you may want to use the scripts installed in the /usr/local/sbin directory. In particular the suite of check- scripts. They will show which IP addresses are accessing the server and can be useful in determining if single IP is causing a disproportionate amount of trouble.
