 Every time a user invokes /usr/ucb/mail command on NFS client machine,
 the message is logged on that client machine. But, other kinds of
 messages are never logged, except 'file lock is not supported'.
 clinet machine mount the filesystem 'softly', via auto mounter.

 I re-read a man page of mount_nfs of solaris, and found that
 soft mount may cause unexpected I/O error.

 I'm afraid my situation might be this case ( though the message
 appears very predictable way).
