Here's one to add to the list: running pgbench with a moderately heavy
load on an SMP box likes to trigger a state where the database (or
pgbench) just stops doing work (CPU usage drops to nothing, as does disk
activity). I've been able to repro this on 2 Intel boxes (one a 2 way,
one a 4 way), and a dual Opteron, all running the latest windows binary.
A 50 connection test running 1000 transactions is pretty much ensured to
fail.
I've been unable to produce the same behavior on a single-proc machine.
Please let me know if there's any more info that would be helpful.
