Symptoms

When you run some programs, you may receive the following error message:
STOP: 0x0000001E : (0xC000009A, xxxxxxxx, xxxxxxxx, xxxxxxxx)
KMODE_EXCEPTION_NOT_HANDLED

Cause

This behavior can occur when you run a program that puts a high number of locks on a file. To hold locks, the file system allocates memory from the NonPagedPool. If the NonPagedPool is exhausted, critical allocations requested by other system components cannot be satisfied, generating the STOP error message.

Status

Microsoft has confirmed this to be a problem in Windows NT version 3.51. We are researching this problem and will post new information here as it becomes available.

Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
S E R V P A C K

More information

The size of the NonPagedPool is calculated in proportion to the amount of physical RAM in the computer. The number of possible locks is directly related to the size of the NonPagedPool. For example, on a computer with 32 MB of RAM, this behavior has been noted after more than 160,000 locks are set.

To correct this problem, Windows NT now reports an error to the program that is issuing the locks.
