Hi, I am monitoring few log file on a windows 2012 server using im_file Send them to an ELK cluster

When checking the indexed logs we noticed delays ( 30 sec or more) for some ( not all) The only clue I have found is a bunch of this type of error

2019-01-28 14:50:01 DEBUG future event, event thread sleeping 34361ms in cond_timedwait

Any idea what that means and how to troubleshoot it ??

Many thanks Steven
