Objet : [THIN] Citrix Farm crash analysis
 
All-
Today, our Citrix farm went down.  Well, at least logins through the web 
interface died.  The actual symptom was that when people tried to log into the 
Web Interface, they got the error message, "ERROR: The supplied credentials 
could not be validated. Either they are incorrect, or there is a problem with 
the authentication system. Try again, or contact your help desk or system 
administrator for help."
Then we noticed that our Data Collector started to act "funny" - that all of a 
sudden there were no active sessions on it.  So we tried to disable logins on 
it (in order to diagnose) and got the attached error message ("The value 
entered for "maximum memory to use for each session's graphics" is invalid.  
Please enter a value between 150 kilobytes and 8192 kilobytes.  Error code: 
51a").  
Meanwhile, people who were already logged into Citrix seemed to continue on OK, 
except of course for people trying to log in.
We rebooted the Data Collector, and the credentialing error on the web 
interface went away, and people were able to log in again.
Currently, our only suspicion is that someone was using the Management Console 
at the exact time that a network error occurred, severing their connection.  
Could a lost RDP connection have resulted in a horrendously bad setting on the 
data collector, resulting in failed logins?
 
Anyone?
 
Thanks
Josh
