Out of? Did the OOM-killer actually show up, or did you simply see memory usage rise? The dcache is tenacious. dentries are cached pretty aggressively, and those in turn will pin the vfs/xfs inodes. But memory is there to be used; unless you actually see problems, then the system is likely working as it should be. <snip> > Note: FWIW Un-mounting the filesystem also recovers the memory. Yep, that would clear out the cache. -Eric _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
