Package: src:linux Version: 4.5.4-1~bpo8+1 Severity: normal NFS seems to have been getting progressively less and less reliable in kernels>~4.0. The latest manifestation on that for me is that having an remote NFS machine go down today, and even after it came back up, 50 instances of /usr/lib/sysstat/sadc (5 minute cronjob) and a dozen df's are stuck on the machine trying to access that remote mount. What are they stuck on? strace shows they're not succeeding in reading /etc/mtab = /proc/mounts: ... open("/etc/mtab", O_RDONLY|O_CLOEXEC) = 3 fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0 mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f67f044e000 read(3, 0-2-19:08:40, Sun Jul 10 root@dirac:/home/tconnors (bash) 73854,15> l /etc/mtab lrwxrwxrwx 1 root root 12 May 29 17:00 /etc/mtab -> /proc/mounts
