Hi everyone,
my JIRA instance is running for 1month now without any restart. A user told me today that since a few days, the agile boards (SCRUM) don't refresh automatically anymore when he creates a new sub-task in the issue detail view screen.
Instead after creating a sub-task, a message appears that says:
Your sub-task ABC-123 has been created but is not currently visible
He says if he waits for ~60 seconds and refreshes the the site himself (by pressing F5), the sub-task appears under the parent issue on his board. The Board filter has not been changed.
Has anyone experienced something like this before? I tested it on my staging environment and there the automatic refresh still works.
We are running JIRA 5.1.5 and Agile 6.3.2.2
Are there any caches that could be full or do you just need to restart JIRA from time to time (like windows) ? 
Thanks in advance!
Cheers
Florian
