We've suffered months (years?) of server problems. Of our 8 instances on two servers, we are nearly every day having to restart one or two instances just to clear whatever's going on.
The symptom is that users usually get a login screen that's not complete, so they can't log in (the load balancers keep putting them on the same server and instance) and complain to us. It seems clear to me the javascript isn't completing when that happens.
A typical stack log entry looks like this:
In some other detail logging with an error log, this is often preceded by a whole bunch of these before the errors begin:
We're currently on 7715-5579, and really hesitant to go through the upgrade process anytime soon. Our last effort to upgrade just landed us stuff like this despite our best testing efforts.
Anyone else having similar problems or have any suggestions for fix?
