Coreservicesd / lssave continues to write every 30 seconds

Yesterday I noticed that some things continued to be written with a gap of 1.48M / s every 30 seconds through the activity monitor. Then I close all unnecessary processes, it is still there. I switched the user, which also did not make sense. Then I did some searches and learned how to use iotop for monitoring.

This shows that a process called "lssave" is written every time every 30 with different PIDs each time. But they have the same PPID, this time PPID [28]. I use ps -ef to search, PID 28 guy is System / Library / CoreServices / coreservicesd.

I can’t make any progress, because when looking for this guy all the results relate to some non-local things.

The version of my Mac Lion is 10.7.3. Free memory more than 5G. It matters because I want to switch to SSD.
