I'm running with NFS root, no swap. Normally at idle I use about 20MB of memory. When I run LTP everything is fine until it hits the rename14 test. Invariably during that test the OOM killer kicks in. With a bit of digging the culprit appears to be the dentry_cache. The last log I have shows it using 817MB of memory. Right after that the oom killer kicked me off the system. When I logged back in, the cache usage was back down to normal and everything was fine. Anyone have any suggestions?
