ls trava no ponto de montagem do NAS

1

Frequentemente estamos nos deparando com esse problema.

nossos pontos de montagem NAS funcionam perfeitamente e, de repente, trava.

quando vamos e fazemos ls trava o terminal.

strace ls / srv / git

trava aqui

 unmap(0x7f6a5c03f000, 4096)            = 0
 open("/usr/lib/locale/locale-archive", O_RDONLY) = 3
 fstat(3, {st_mode=S_IFREG|0644, st_size=99158576, ...}) = 0
 mmap(NULL, 99158576, PROT_READ, MAP_PRIVATE, 3, 0) = 0x7f6a5619e000
 close(3)                                = 0
 ioctl(1, SNDCTL_TMR_TIMEBASE or TCGETS, {B38400 opost isig icanon echo      ...}) = 0
 ioctl(1, TIOCGWINSZ, {ws_row=28, ws_col=117, ws_xpixel=0, ws_ypixel=0}) = 0
 stat("/srv/git",

^C <unfinished ...>

ps -ef | grep ls

nos dá muito desse processo
