The warnings about setting the date are not very important. To get rid of those warnings, you need to synchronize the date on all machine.
The “connection refused” error occurs when the web server is overloaded. To make sure it is the case, you can start with a low number of clients (e.g.,5). If the test run finishes without any “connection refused” errors, you need to tune the number of nginx and php worker threads as described on the CloudSuite page, as well as the number of clients. Meanwhile, you should check the server machine utilization (e.g., with top). If the utilization is higher than 85-90%, the server machine is overloaded and you need to reduce the number of clients. -- Cansu On 03 Apr 2014, at 17:04, reza azimi <[email protected]<mailto:[email protected]>> wrote: Thanks Cansu for your reply. I solved the problem of php timezone. I thought timezone in php.ini is not important so I set it to default Zurikh during the installation. Now I set it to New York and we are fine ( we are at the same time zone with New York) about the connection, the problem was not the ssh but your concern raised a question in my head. We changed the /etc/network/interfaces for another experiment and I forget to get it back to normal. the error from last time are gone but we have other errors. Can you take a look of it and see which part is not functioning correctly?? I've attached the first three pages of the log, let me know if you need information from other pages. Thank you for your help. Regards Reza <1.jpg><2.jpg><3.jpg>
