Excessive consumption of users in Overselling mode

    How much of the quota are they going? The quota is going to allow a small amount of grace per account.

    More details on that feature can be found here: cannot create any new accounts." Does that help clear things up?

    Overselling basically removes the ability of the system to govern the reseller's limits. It becomes a task for the server administrator to govern the usage with overselling enabled. A reseller with a 10GB disk space limit without overselling, is able to allocate out 10GB worth of disk space to his resold accounts. That could be ten 1GB packaged accounts, twenty 500MB packaged accounts, or some combination. The system won't let the reseller allocate more than 10GB of total disk space among his resold accounts. How much actual disk space the resold accounts use is irrelevant, because the restriction is allocation based. But the absolute maximum that those combined resold accounts could ever use is 10GB Enabling overselling effectively removes that governance. A reseller with a 10GB disk space limit and overselling enabled can create accounts with packages sized at 1GB, 5GB, 10GB, 100GB, 1000GB it doesn't really matter. Nothing stops the reseller with overselling from over allocating his 10GB disk space limit. That means a resold account under this reseller could use 1000GB despite the reseller's 10GB disk space limit. So why even have limits if overselling is enabled? So that the server administrator can keep tabs of what limits a respective reseller is suppose to be held to. How you do that is up to you. We don't have a lot of overselling reseller plans, but the ones that we do, I created a daily report that tabulates how much cumulative disk space a reseller's accounts are using and compare that to the reseller's disk space limit. When a reseller's cumulative total exceeds their defined disk space limit, we write the reseller and may suspend the reseller's accounts until the issue can be rectified. Effectively we make this a usage based reseller vs. an allocation based reseller. Allocation based resellers are fixed cost. Since resellers can't over allocate, they can never exceed their disk space limit. That means those resellers know exactly what they are going to be paying every pay period. If they need more disk space to allocate out, then they will have to upgrade - again knowing the cost. Usage based resellers are not fixed cost. Since those resellers never know when their resold account's cumulative disk space is going to go over their disk space limit, they can never be sure what their cost is going to be from pay period to pay period. From a server administrator's point of view, usage based resellers are more expensive than allocation based resellers. Allowing a reseller to allocate out 10GB of disk space, means that those accounts are very unlikely to ever consume a total of 10GB. Not saying it's not possible, but it's unlikely. Whereas a reseller with a usage based 10GB reseller plan, they are free to create as many accounts (within account limits) as they want regardless of how much disk space is allocated. That reseller is only going to be forced to upgrade once they hit 10GB of total cumulative disk space used.
