Handle Leak in SNAUDB.EXE

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

A supported fix is now available for 3.0 SP2 and 4.0, but has not been fully regression-tested and should be applied only to systems experiencing this specific problem. Unless you are severely impacted by this specific problem, Microsoft recommends that you wait for the next Service Pack that contains this fix. Contact Microsoft Product Support Services for more information.
