I know, but it can not allocate all the cache memory, so you will fail sometimes if the memory has not been reclaimed. ? 2012-02-17 15:13:18?"Wang Chao" [off-list ref] ???

I know this, but I want to reclaim dynamically. Say in a shout time, several seconds.Why do want to do that? Does it have a bad influence on performance? Kernel will reclaim these cache itself when your machine runs out of mm.quoted

Hi I encounter a problem recentely. My system supports USB strorage and other network applications. But after I put a file to usb storage, it will consume some many momory. (buffer + cache). And these buffered memory can not be reclaimed(use free command). So I want to know how to reclaim the buffer memory in a short time.Google for ./sys/vm/drop_caches -- Thanks - Manish _______________________________________________ Kernelnewbies mailing list Kernelnewbies at kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbiesquoted
