Performance counters disappeared

I have an application written in C++ that querys all
available performance counters via RegQueryValueEx() API
at 10 second interval on some Windows 2000 computers that
have SQL Server 7.0 installed. After the application have
run for some period of time (several days or longer), the
SQL Server related performance counters disappeared. They
are disabeld by the OS. The knowledge base article
Q248993 mentions that the performance library of Windows
2000 disables any performance DLL that returns data in the
incorrect format, causes an unhandled program fault, or
takes too long to return the performance data (this is
usually the cause of a library being disabled). It is
obvious the incorrect format does not apply to my case
since it would have caused the problem right after it
started not several days later. Anyone knows what causes
the problem?Did you see Q812915?

the help.
