Handle Leak in SNAUDB.EXE

• Microsoft SNA Server, versions 3.0, 3.0 SP1, 3.0 SP2, 4.0

SYMPTOMS

SNA Server Host Account Cache service (that is, SnaDatabase, or Snaudb.exe) handle count grows each time a new logon request occurs. This problem can be observed by monitoring the handle count for the snaudb process using the Windows NT performance monitor. Eventually, the Host Account Cache service will fail, causing host user ID's and passwords to fail to be mapped.

CAUSE

The SNA Server Host Account Cache service (Snaudb.exe) was not closing the event handles it created for every RPC request it received.

STATUS

Microsoft has confirmed this to be a problem in Windows NT SNA Server, versions 3.0, 3.0 Service Pack 1 (SP1), 3.0 SP2, and 4.0.

This problem was corrected in the latest SNA Server versions 3.0 and 4.0 U.S. Service Packs. For information on obtaining these Service Packs, query on the following word in the Microsoft Knowledge Base (without the spaces):
