Description
We have seen multiple problems in our Release environment in the past 24 hours. Twice the UI has become unresponsive. The logs show the same pattern each time. Attached is the log file. Some examples are listed below.
Preliminary health checks indicate that the servers are not under serious load at the time of the issues. We are continuing to investigate on our side, but please take a look at our logs and let us know if you need any more information.
Thanks.
