Created attachment 1665557 [details] export glusterfsd statudump after stop fio and remove fio files Description of problem: doing IO from 10 glusterfs clients at the same time, glusterfsd memory consumption grows, after io finish the glusterfsd memory does not drop anymore. Version-Release number of selected component (if applicable): glusterfs7 How reproducible: Steps to Reproduce: 1.begin IO with fio on 10 glusterfs clients at the same time 2.observe memory usage of glusterfsd 3.finish IO, and remove IO files Actual results: glusterfsd memory keeps to be high # ps -aux | grep glusterfsd| grep export root 2643 84.8 20.2 2358828 412908 ?
