There will be a DB restart in about 30 minutes, around 12:30 UTC
It will actually be when the zekken shift completes and is processed - which will be about then.

No mining will be affected at all.

The web site and API will reply with lotsa zeros and '?' marks during a DB restart, for about 10 minutes.

This is a minor update to try and deal with the timeouts that occur every once in a while - and I'll now mention the actual cause since I've implemented a way to deal with them
The rewards and payouts pages go back to when the pool started for some miners.
The data back then gets swapped out of ram and sometimes when a long term miner checks their rewards and payouts, it takes too long to swap back into ram and times out on the web page.
I think the actual cause is if two different people do it at the same time - which would also explain why it's not very common.
This change helps stop that data from ever swapping out, since the DB now runs with a RES footprint smaller than bitcoin and a VIRT size smaller than ckpool, it's OK to stop that data from being swapped out.

I'll post again once the DB restart has completed.
