Thanks to those that replied.
Found the culprit! Our hot standby machines can use either
Ethernet or Encore Reflective Memory cards for the
replication channel.
When we use reflective memory, the standby machine
slows down by ~10 seconds per hour. The rate of the slow
down varies depending on system activity.
When we use Ethernet everything is fine.
Therefore it appears that a badly written driver is getting
in the way of clock interrupts and slowing the system down.
FYI the driver is Encore's PRM220 (that's version 2.2.0).
Other people that use this reflective memory might want to
worry about this ....
P.S. Can anyone that uses Encore Reflective Memory (if there
are any) get in contact with me please? It would be nice to
know that we aren't alone!
