SYMPTOMS
When you call the StartTrace function, you may receive a &quot;Stop 0x0000001E&quot; error message. This error message occurs if the minimum number of buffers in the EVENT_TRACE_PROPERTIES structure is set to a value that is less than the number of processors in the computer. The stack for the error is similar to:

CAUSE
For the trace to succeed, you must allocate as many buffers as there are processors in the computer. Allocating too few buffers causes an error message.
