Source: MSExchangeIS
Category: Content Engine
Type: Error
Event ID: 12800
Description:
Message processing failed because there is not enough available memory (8007000E-8200022D). For more information, click http://search.support.microsoft.com/search/?adv=1.Even though initial troubleshooting analysis indicates an out-of-memory condition, when you perform additional analysis, an access violation occurs.

CAUSE

This issue occurs because the OMSG::EcFlushProps function tries to flush a recipient object that has not yet been initialized when a low memory condition exists.

When the information store opens an existing message, an OMSG object is created. The initialization of the OMSG object is done by the OMSG::EcConfig2 function. The OMSG::EcConfig2 sets several properties. However, if a low memory condition exists when the OMSG::EcConfig2 function sets one of these properties, Exchange 2000 tries to flush the properties on the OMSG object before an out of memory error is reported. An access violation occurs when Exchange 2000 tries to flush a recipient object that has not yet been initialized.
