-----------------------------------

I don't completely understand this problem. Is this a collector or agent problem? Can you explain in a bit more detail?

> The existing adaptor might not retrieve data because agent was designed to loop through the adaptors to send the information.  When the frequency of registering and unregistering is more frequent than chunk writer, like many tasks attempting to stream their metrics over, the existing adaptors do not get loops.  The easy workaround is to have socket appender ready, and we don't need to worry about this issue.  However, this is still an general issue, if the chunk writer write time is longer than registration interval with high registration frequencies.
