It is normal behavior. According to documentation the checkpointing process could be triggered by the timeout( 3min by default) or the size of the checkpointing buffer. In your case every 3 mins Ingite starts the checkpointing process to sync dirty pages from RAM on disk. The log message indicates there are not dirty pages in RAM.
