Re: RE: Loosing half the monitor callbacks

Hi Friends Kay, Mark and Mohan,

Thank you very much for the advices.

I just tried camonitor.  It is doing the same thing: throw away every the other
change, but callback two times for the other ones.  The printout is like:

fastTimeTest.CTME              2008-08-08 16:46:02.609123 6.88202e+06 
fastTimeTest.CTME              2008-08-08 16:46:02.859123 7.38478e+06

fastTimeTest.CTME              2008-08-08 16:46:04.059123 817524 
fastTimeTest.CTME              2008-08-08 16:46:04.059123 817524 

Does the record update time stamps tell anything?  Am I running too fast?

Thank you again.  Best regards,
Dehong
