https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211674 Bug ID: 211674 Summary: sysutils/fusefs-ntfs: fuse_vnode leak/reclamation failure Product: Ports & Packages Version: Latest Hardware: Any OS: Any Status: New Severity: Affects Many People Priority: --- Component: Individual Port(s) Assignee: freebsd-ports-bugs@FreeBSD.org Reporter: mqudsi@neosmart.net CC: freebsd@dussan.org CC: freebsd@dussan.org Flags: maintainer-feedback?(freebsd@dussan.org) SUMMARY Running on FreeBSD 10.3-RELEASE-p6/i386 with fuse compiled into kernel and = with fusefs-ntfs 2016.2.22 installed, there is a fuse_vnode leak (though it seem= s it may be more of a complete failure to reclaim vnodes) resulting in quick resource exhaustion. REPRODUCTION This is easily reproduced with the following: ntfs-3g /dev/xxx /mnt/yyyy cd /mnt/yyyy find . -exec touch {} \; In another virtual terminal: vmstat | head -n1; vmstat -m | sed 1d | sort -hk 3,3 ACTUAL RESULTS fuse_vnode will continuously balloon, and will not be reclaimed until the filesystem is unmounted. (likewise, fuse_msgbuff also balloons but unlike fuse_vnode, it is never reclaimed. Separate PR?) EXPECTED RESULTS fuse_vnode entries should be reclaimed ADDITIONAL INFORMATION Here's a snapshot of the fuse-related vmstat entries after this process: fuse_vnode 36020 9005K - 502349 256 fuse_msgbuf 58141 14895K - 311095 256,512,1024,2048,4096,8192 --=20 You are receiving this mail because: You are the assignee for the bug.=
