Have you tried sending admin a PM so they notice it?
When we were having issues with M/Cluster we had to disable it a while back, even with the new database config there are a few issues, so as we stand the site is running pretty well on the master/master config, next step is to drop in a couple of slave servers to help with the more intensive queries such as photo ads searches and session logging, with that comes the who is online/offline and where are they.
I'm not sure on timescales but it is on our urgent development plan so hopefully we are talking weeks and not months.
For vanilla's you lot sure know a lot about Masters and Slaves :giggle:
And don't talk about using a packet sniffer! :shock:
