[Moosefs-users] master restart error

[goubao.163 <gou...@16...>]

hi all:
        mfs version 1.6.17
        In my mfs system,there are sixty million files . when i stop master and then start it , a error occured . the error log is that 
loading chunks data ... error . error was find in chunks.c function chunk_load(FILE *fd)
r = fread(loadbuff,1,CHUNKFSIZE*CHUNKCNT,fd);
  if (r<0) {
   return -1;
  }
  if ((r%CHUNKFSIZE)!=0) {
   return -1;
  }
why?
