Well -
This has just started to happen now that we launched a new module
that is more transaction intensive. Our concurrent users have also
been boosted. It is mySQL on a Mac Mini runing TigerOSX Server with
1Gig. Don't laugh, amazing it has gone this far! I will try turning
on another instance and see. There was nothing in my log files...
they just stopped with nothing out of the ordinary.
Anyway my next step is to move deployment to Linux. Any suggestions
here? Redhat? JavaMonitor or jBoss? Licensing?

We very rarely run a single instance.
Is there any advantage in running more than one instance on the
same server?
Advantage? We only run a single instance if we are desperate for
memory! Running multiple instances allows you to process higher
loads (EOF is only single threaded within the instances) and
provides for much better availability. With only a single
instance, if you recycle it your site is out until it restarts. As
single instance is only for memory starved machines and very low
traffic sites.
