SYMPTOMS
Delayed worker threads may cause a STOP 7A - KERNEL_DATA_INPAGE_ERROR message to be displayed.



CAUSE
When the browser receives a server announcement, the transport notifies the browser at the interrupt level. This announcement is queued to a worker thread by allocating a block of non-paged pool for the work item and queuing that work item for later processing.

If the announcements arrive very quickly or if the computer running the browser is very busy, the work items are not processed as quickly as they are received. In that case, all of the non-paged pool memory is consumed by these queue entries.



RESOLUTION
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
