Concurrent "INSERT INTO jiveProperty" Problem

I tried to update (technically it’s add) a jive global property in admin consoles on different cluster nodes. It was successful on the first node, the next failed. The log showed duplicate key error, so I guess it’s a mixed cache + INSERT statement problem. I tried this on “HTTP Binding” page (httpbind.enabled property). It may happen in other similar situations. If clustering is a big leap, so as the bug. Otherwise it’s probably minor
