DHCP Server Leaks Registry Quota on Alpha Version of Windows NT
Article ID: 184744 - View products that this article applies to.
This article was previously published under Q184744
A DHCP server running on an Alpha server causes Registry Quota to be leaked over time. This may result in degraded system performance or the following STOP error message:
Stop 0xc000021a e17c7fc8 00000000 00000000
This issue only occurs on Alpha versions of Windows NT 4.0 with DHCP server installed. The problem is caused by allocating more memory than is deallocate when saving registry keys. DHCP server periodically leaks Registry Quota during normal operation, approximately .065 KB every 10 minutes using PerfMon statistics. This problem is amplified by repeatedly starting and stopping the DHCP service. The service was found to have 2 leaks, each leaking 2 KB every time the service was started and stopped.
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:
