Of course the cache doesn't go away when he uses sync! Why should it? Its a cache not a buffer. Instead, it grows and grows...
As others have said, the cache will grow to use all available memory
That is a GOOD THING for a cache to to.
Even when that messes up running app requests for memory? It has been said that if memory is needed by some app, this cache may get smaller to accommodate. I am not sure that is the case. When memory use gets big, some apps die.
Roger, if that were true, we'd all be in big trouble. The use of spare memory for file systems cache is purely opportunistic - if an app needs memory, it will get it. Provided there is free memory, of course - but "free memory" includes memory used for cacheing. -- Per Jessen, Zürich (17.9°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
