If I set vm.overcommit to 3, add a rctl(8) rule of the form user:u:swapuse:deny=32M, log in as user u and read a man page, the memory limit triggers and the system freezes, afterwards rebooting. Lower memory limits (like 1M) work as expected, as do higher memory limits (like 256M), but the 32M limit is crashing the system. Any help would be appreciated.
