How do I unsubscribe from this list.

I have tried everything including doing what it says at the bottom of the messages about sending a message to majordomo with unsubscribe and my email address as the header.

Nothing is working.

Please help.

Cheers

Tom

You mentioned that you'd see the problem during a large number of concurrent transactions. My question is, is this a necessary condition for the database crashing when the plug was pulled, or did you need use a large number of concurrent transactions to "guarantee" that when you pulled the plug, that it would be at an inopportune time? In other words, is an IDE drive still "more" susceptible to a power outage problem even under light load?



A heavy load makes it more likely that you'd see the problem, but only because it improves the odds that there will be data "in flight" at the instant the power drops. You can still lose on a lightly loaded system if your luck is bad.
