Hi Edward, Alan,
I plan to commit the following patch:
http://people.freebsd.org/~jlh/racct_munlock.diff
This solves the following panic:
panic: racct_sub: freeing 301989888 of resource 5, which is more than allocated 73728 for pwsafe (pid 4177)
The problem is that the racct code in sys_munlock() trusts too much the
user's input. vm_map_unwire_count() now returns how much memory has
really been unwired.
Any objection?
