A small side note (probably not related to your actual
problem): It is usually a bad idea to use the -s ("soft")
option, because many programs are not prepared to handle
unexpected I/O errors, leading to file corruption.
The following is an excerpt from the Solaris docs, which
applies to FreeBSD as well:
| File systems that are mounted read-write or that con-
| tain executable files should always be mounted with
| the hard option. Applications using soft mounted file
| systems may incur unexpected I/O errors, file corrup-
| tion, and unexpected program core dumps. The soft
| option is not recommended.
I think a similar paragraph should be added to FreeBSD's
mount_nfs(8) manpage and to the Handbook.
Best regards
Oliver
