Are you referring to the implementation of RLIMIT_SWAP in the overcommit-disable patch at: http://people.freebsd.org/~kib/overcommit/index.html ...or some other as yet unwritten implementation? That patch doesn't currently do 90% of swap but easily can. That's been available for almost 3 years now. I tested it at one point but not lately and it never went into production. Do you, and others, have a problem with that implementation? -- SkipReceived on Fri Jan 04 2008 - 12:53:37 UTC
