Before you start juggling filesystems, perhaps verify that the data on that filesystem is where it belongs...
Check for dangling filehandles - compare the output of du -sk /usr and df -k /usr, if the du output is significantly lower, you've probably deleted a file but left a process using the handle. Use lsof (or fuser, /proc or pfiles) to locate the process that is holding the handle and restart it.
Look for the big blobs in /usr - du -sk /usr/* | sort -n will show you the largest directories in there, you can drill deeper from there as required.
Look for recently modified files - /usr should be fairly static, if something is changing frequently, maybe it doesn't belong in there. find /usr -mtime -10 will show files modified in the last 10 days.

lint(1B) SunOS/BSD Compatibility Package Commands lint(1B)
NAME
lint - C program verifier
SYNOPSIS
/usr/ucb/lint [options]
DESCRIPTION
/usr/ucb/lint is the interface to the BSD Compatibility Package C program verifier. It is a script that looks for the link
/usr/ccs/bin/ucblint to the C program verifier. /usr/ccs/bin/ucblint is available only with the SPROcc package, whose default location is
/opt/SUNWspro. /usr/ucb/lint is identical to /usr/ccs/bin/ucblint, except that BSD headers are used and BSD libraries are linked before
base libraries. The /opt/SUNWspro/man/man1/lint.1 man page is available only with the SPROcc package.
OPTIONS
/usr/ucb/lint accepts the same options as /usr/ccs/bin/ucblint, with the following exceptions:
-Idir Search dir for included files whose names do not begin with a slash (/) prior to searching the usual directories. The
directories for multiple -I options are searched in the order specified. The preprocessor first searches for #include files
in the directory containing sourcefile, and then in directories named with -I options (if any), then /usr/ucbinclude, and
finally, in /usr/include.
-Ldir Add dir to the list of directories searched for libraries by /usr/ccs/bin/ucblint. This option is passed to
/usr/ccs/bin/ld. Directories specified with this option are searched before /usr/ucblib and /usr/lib.
-Y P, dir Change the default directory used for finding libraries.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/usr/lint/bin/ld link editor
/usr/lib/libc C library
/usr/ucbinclude BSD Compatibility directory for header files
/usr/ucblib BSD Compatibility directory for libraries

/usr/lib/libsocket library containing socket routines
/usr/lib/libnsl library containing network functions
