The overloaded state is based on a series of resource utilization metrics: http://exchangeserverpro.com/exchange-transport-server-back-pressure/ Free disk space on the drive(s) that store the message queue database and logs Uncommitted queue database transactions in memory Memory utilization by the EdgeTransport.exe process (the Microsoft Exchange Transport service) Overall memory utilization for the server Each of those metrics is measured individually, and as such each is individually capable of causing the server to go into a back pressure state. There are two different levels of back pressure. as well as the condition where no over-utilization is occurring, so in total there are three resource utilization conditions that your Edge or Hub Transport servers can be in: Normal - all is well and the server is performing its role as intended (assuming you haven't modified the back pressure settings to mask a genuine problem - more on that later) Medium - a resource is moderately over-utilized and the server begins limiting some connection types. Typically internal email flow remains functional while email from external or non-Exchange sources will be rejected. High - a resource is severely over-utilized. The server ceases to accept any new connections. For disk space metrics the back pressure condition causes messages to be rejected. However for memory utilization metrics, before rejecting connections the s
15 Dec. 2011] Completing a look at the feature known as Back Pressure in Exchange 2010. If you would like to read the first part in this article series please go to Back Pressure in Exchange 2010 (Part 1). Introduction In part one of this two-part http://www.msexchange.org/articles-tutorials/exchange-server-2010/management-administration/back-pressure-exchange-2010-part2.html article on the back pressure feature in Exchange Server 2010, we covered the calculations that Exchange uses to determine the high, medium and normal back pressure levels for disk utilization. Here in part two we’ll look at how a breach of these https://www.experts-exchange.com/questions/26473799/Exchange-2010-Back-Pressure-Inbound-mail-stopped-Event-ID-15004.html levels will look as far as the Event Viewer is concerned as well as covering how things look when trying to telnet to a transport server to manually submit a new SMTP message. We will then finish by looking at the back pressure back pressure settings for memory utilization. Event Viewer Let’s start part two by having a look at what we see in the Event Viewer when a back pressure event has occurred that has been caused by a lack of disk space. In Figure 2-1, we can see event ID 15004 from a source of MSExchangeTransport that informs us that the resource pressure has increased from normal to high. Figure 2-1: Event ID 15004 – High Back Pressure Event You can see from Figure disable back pressure 2-1 that two separate resources are detailed, namely the disk space utilization associated with the queue database and queue database transaction logs. Specifically, you can see that the disk space utilization associated with the queue database is shown as 96%, as is the disk space utilization associated with the queue database transaction logs. This is because these two resources are located on the same disk. We can also see from Figure 2-1 that the 96% utilization for the queue database disk is rated as medium usage. After this, we see that the normal, medium and high utilization percentages are stated as 93%, 95% and 97% respectively, as covered in part one of this article. Remember, these values are based on an example disk partition size of 20GB. Immediately below this information, we can see that the 96% utilization for the queue database transaction log disk is rated as high usage; therefore this event has been logged because the queue database transaction log disk has moved from normal to high usage not because the queue database disk has moved from normal to medium usage. After this information, we see that the normal, medium and high utilization percentages for the queue database transaction log disk are stated as 88%, 90% and 92% respectively, as covered in part one of this article. Again, these values are based on an example disk partition size of 20GB as the queue database and queue database transaction logs are located on the same disk. Scroll

A Windows error is an error that happens when an unexpected condition occurs or when a desired operation has failed. When you have an error in Windows, it may be critical and cause your programs to freeze and crash or it may be seemingly harmless yet annoying.
A stop error screen or bug check screen, commonly called a blue screen of death (also known as a BSoD, bluescreen), is caused by a fatal system error and is the error screen displayed by the Microsoft Windows family of operating systems upon encountering a critical error, of a non-recoverable nature, that causes the system to "crash".
One of the biggest causes of DLL's becoming corrupt/damaged is the practice of constantly installing and uninstalling programs. This often means that DLL's will get overwritten by newer versions when a new program is installed, for example. This causes problems for those applications and programs that still need the old version to operate. Thus, the program begins to malfunction and crash.
Computer hanging or freezing occurs when either a program or the whole system ceases to respond to inputs. In the most commonly encountered scenario, a program freezes and all windows belonging to the frozen program become static. Almost always, the only way to recover from a system freeze is to reboot the machine, usually by power cycling with an on/off or reset button.
Once your computer has been infected with a virus, it's no longer the same. After removing it with your anti-virus software, you're often left with lingering side-effects. Technically, your computer might no longer be infected, but that doesn't mean it's error-free. Even simply removing a virus can actually harm your system.
