Comment 8 for bug 633140

All those affected by this bug, can you comment with what your refresh interval is set to? And if it is under 10 minutes please bump it up to 10 minutes and see if it happens again.

I suspect when there are network related issues, which prevent a full refresh from completing before the next scheduled interval, it blocks. However, those threads doing the work should time out after 240s, but we have seen bugs in the past where the timeout wasn't killing the thread.
