If SIRAS is unresponsive or "freezing", there are several possible causes, but usually this is related to an interruption with the network or Internet connection.

• If too many tabs are open in your browser it will consume its ability to efficiently process data and can be slower, possibly causing time outs, and/or other unusual behaviors. The solution is to close all other non-essential tabs on your browser.  Closing all browser windows and other programs, or even restarting the computer, will often resolve issues related to limited CPU resources.  If slowness and problems persist outside of Siras, it may be a good time to contact your IT department.

• If you are connected to a Wi-Fi, confirm that you have at least three bars or an excellent connection otherwise you may experience disconnections. If there are too many computers on the Wi-Fi, you will also experience some performance issues.  Sometimes these disconnections won’t be obvious until the page refreshes. Solution is to position your computer where the Wi-Fi access is strongest.

• If this is happening at school, it may be related to the district firewall or DNS server disconnected the session.  This can be very problematic as the program has been disconnected yet the program is still loaded in the browser cache and will seem to act normally until some point where SIRAS becomes non-responsive.  Usually everyone in the school will have similar issues. The solution would be to contact and describe the issue with your IT department.  SIRAS Systems will work with them to assist in resolving. A question to ask is: How long IP addresses are good for in the DHCP setup.  Expired DHCP sessions will take you off line while the browser still appears to be online temporarily.  If a DHCP address is good for less than 12 hours, that may be a problem.
