The root cause is in the hugepage segment handling code. Example. # lsof -p PID | grep -c rtemap=20 1494 Each fd there is counted twice, once as an fd, and once as an mmap. So in this case 747 file rtemap files are left open. --=20 You are receiving this mail because: You are the assignee for the bug.=
