DescriptionNotifications for the scope \\ServerName\ShareName\ have been reactivated.
Event InformationAccording to Microsoft:
CAUSE:

This behavior can occur because there is a buffer size limit of approximately 2,500 change notifications for the operating system. When Microsoft SharePoint Portal Server 2001 or Microsoft Office SharePoint Portal Server 2003 uses remote notifications this limit may be exceeded, after which the cache error occurs.
WORKAROUND :
To work around this behavior, use the following guidelines:
• If content is frequently changed, configure the content source for crawling instead of for notifications.
• If content is seldom changed, configure the content source for notifications instead of for crawling.
The latter method only functions well in scenarios where a buffer overflow is not occurring. After SharePoint Portal Server detects that notifications were missed, SharePoint Portal Server implements incremental crawls.
MORE INFORMATION:
To view additional information about the types of crawls available in SharePoint Portal Server:
1. Open the SharePoint Portal Server Administration tool.
2. On the Help menu, click Help Topics, and then click the Search tab.
3. In the Search box, type Adaptive, Incremental, or Full.
4. Click List Topics.
