CPU Use at 100 Percent with SNA Server 3.0 Print Server (164792)
The information in this article applies to:
- Microsoft SNA Server 3.0
- the operating system: Microsoft Windows NT 3.51
- the operating system: Microsoft Windows NT 4.0
This article was previously published under Q164792 SYMPTOMS
When using SNA Server 3.0 on Windows NT Server 3.51 or 4.0, the CPU use
may reach 100 percent and stay at this value indefinitely. This problem
has only been observed by using SNA Server 3.0's print server, where the
local print processor is not spooling data in a RAW format to a
destination print server. You can observe this CPU use by going into
Performance Monitor and looking at the following counters:
Object: Processor
Instance: 0
Counter: % Processor Time
Object: Process
Instance: snaprint
Counter: % Processor Time
You will see the first counter at 100 percent and the second counter
between 97 to 100 percent indefinitely.
CAUSE
The cause of this problem is currently being investigated.
WORKAROUND
You can use a workaround until a fix can be made to the Windows NT Server
print subsystem. The workaround is to make sure that the print job from
SNA Server is spooled as a RAW datatype to the destination print server.
You can accomplish this by doing either of the following:
- On a Windows NT Server 4.0 client (where SNA Server is running), go
into the Properties for the defined printer. Click the Print Processor
button and check the "Always spool RAW datatype" check box. By default,
this option is not checked.
- On a Windows NT Server 3.51 client (where SNA Server is running),
select the printer in Print Manager, click Properties on the Printer
menu, and click Details. The default datatype needs to be RAW. By
default under Windows NT Server 3.51, the default datatype is RAW.
STATUS
Microsoft has confirmed this to be a problem in Windows NT Server 3.51 and
4.0 and SNA Server 3.0.
This problem was corrected in the latest Microsoft SNA Server 3.0 U.S.
Service Pack. For information on obtaining the service pack, query on
