Recently there has been notably an error associated with the pages except "home". Suspiciously, this could be related to session management issues(speculative).
Once the service is restarted, everything works well. After a certain amount of time (can not tell how much time as at now) we get the error page again.
From the logs, it shows that the server is requesting for a rollback for an operation which didn't complete and also looses connections some times.
Could be closely related to T336837
