EAM plugin cannot sustain high concurrent user load and will be killed by memory monitors. EAM is cored and restarted. Any requests coming during restart will not be served.
As a result, EAM cored and restarted; users cannot authenticate during process restart.
This issue was found internally during in stress testing and was reported externally when experiencing high concurrent user load.
No workaround.
There was a memory usage issue in the EAM plugin. This issue is fixed.
