browser to RT, it hangs when the login page should be displayed. Usually
I’ve just performed a “service httpd restart” to resolve the
problem. This morning, I just let it sit and load for in excess of 20 minutes,
and the page finally appeared, after which RT seemed to be performing fine
– even if I restart my browser and head back to the logon page. This did
happen in the middle of the day yesterday as well, to which I restarted httpd,
as normal. This, obviously, won’t work for production (which we plan on
this system being shortly). I’m sending this message in the hope that
someone can assist me with this problem.<o:p></o:p></span></font></p>
