I've 10gb RAM I get this warning: warning: total configured swap (8960911 pages) exceeds maximum recommended amount (8243200 pages). warning: increase kern.maxswzone or reduce amount of swap. What is max. recommended amount based on? What is the danger of exceeding it? How should I increase kern.maxswzone? # sysctl kern.maxswzone kern.maxswzone: 0 # Do I set it to the total swap size? Where is kern.maxswzone described? Thanks Anton
