site_archiver@lists.apple.com Delivered-To: darwin-kernel@lists.apple.com -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 I'm wondering if there have been significant changes to the memory manager on Snow Leopard? We are seeing situations where the kernel is running out of memory. If the system remains idle for some period of time, then more memory becomes available or at least more virtual memory space becomes available (this is in K32). For example, IOMemoryDescriptor::withAddress( buffer, bufferSize, kIODirectionIn) will fail for 32K but will work for 512 bytes. After some period of time, the 32K will begin to work again. We haven't seen these same sort of issues in Leopard. Is there something we should be doing differently to manage memory in the kernel? ...Duane ps Yes, I will be doing a search for leaks. :-) -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.10.0 (Build 500) Charset: US-ASCII wsBVAwUBSukdIUrg9acQ4r2CAQiDhwgA0yFUVCJRgguFC+9fXD16rLE1T51lrMnt jmme2nSGy8pupvkslHV0uI1P/LaZJfN5RAvA7IvH2tNLIWweeOA0zy+VBGPiPRuv m44JY1S7DJv399R9Jp45Sc9oer1JxMm2C8o9TxUxDrDrYuXcxHQY7WOhP9KmSskY BqAjJn37J70khjtQMJ9HPONW4rA3am+xmcCnDwfONlOWyMgx4hkRtgEYubkA+MSl hSOFEhLl0ywqheEm8xTSyGBl+aQzPEZgc5mvLomWvTIfoZe5Sk8G/PTCgdW5Gcvx JpybbUs0DVqZlw1vXk2YBLeLRa4zws9Hx8dmSZSnmojls6RL+DP2Sg== =PaaA -----END PGP SIGNATURE----- _______________________________________________ Do not post admin requests to the list.
