Hi Anglelia,

On the first place, I was added new comment on a jira's item then it says some think like system error while adding my comment.

Then I reloaded the page and it stops working.

As you see on the log I posted, I was saw that error on every item detail page such as  http://jira.myngle.com/browse/AH-3461. All other page such as dashboard, ... still work well.

I tried to reload from browser many time but it still doesn't work. I had to stop then restart jira services and the issue gone.

Thanks,

DuongTC
