[CentOS] NFS automount error

hi, guys:

  Today when i typed  "mount " command on the server and found  this
message:

..
...
192.168.9.252: /home/share/tmp on /net/tmp/share  type nfs ( rw, bg,
soft,rsize=8192,wsize=8192,addr=192.168.9.252)
192.168.9.252: /home/share/tmp on /net/tmp/share  type nfs ( rw, bg,

This message was  told to  me that the "/home/share/tmp" directory was
mountd repeat more and more times .

I guess it maybe is the NFS problem . But I have no idea of  solving  it .


Could someone give me some suggestions ?  Thanks in advance~
