Authentication Service slow or unresponsive for some users: Thursday, Oct. 7, 2013 11:56 AM – 12:15 PM

Posted on October 7, 2013 by Hongbo HE

Ryerson’s Central Authentication Service (CAS) became either slow or unresponsive for some people trying to use it at 11:56 AM this morning.  CAS controls the login process to my.ryerson.ca, Google Apps at Ryerson, and other services. We found that one of the CAS servers ran out of application memory. The CAS server was assigned more memory and restarted. As a precaution, the other CAS servers were also assigned more memory. The system has been working normally since 12:15 PM. We are investigating what caused the process to run out of memory.

Please accept our apologies for the problems this outage caused.
