Update on August 3, 2015: It's still happening, on individual posts that have had recent activity.
Clicked on "Answer the question".
Saw "Waiting for sqlanywhere-forum.sap.com..."
Waited waited waited waited waited...
Abandoned the attempt (closed the page) after several minutes...
Redisplayed the forum home page.
Saw the message "You answered LoganTennis on How to list exceptions created in database via "CREATE EXCEPTION"".
Exclaimed "WooHoo! It worked!"
Clicked on the entry that now shows at the top, with "2 answers" instead of one "How to list exceptions created in database via "CREATE EXCEPTION""
Saw "Waiting for sqlanywhere-forum.sap.com..." again...
Posted THIS message, separately, no problems.
Still can't open the other one.
I have seen this frustrating behaviour on several occasions myself but I have been unable thus far to determine a cause. Restarting the Apache server solves the problem but that's a bit heavy-handed. I am still investigating.
Update: I have fixed the hanging problem. When you answer or comment on a question, the system automatically subscribes you to the question. The attempt to autosubscribe was hanging because another thread had already tried to do it but then hung around forever without doing a commit.
