Hi, I'm running an interesting test case where I can cause an instance of cosd to use all available memory on its server. On the server side I'm running the testing branch (at commit 817495d2). On the client side I'm running the for-linus branch (at commit 240ed68e). Client and server are both CentOS 5.5. My filesystem has one monitor daemon, two mds daemons, and one osd daemon, all running on one system with 4 GiB memory. I'm running with no swap, because otherwise during this test the system swaps like mad and becomes unresponsive. The swapping is what made me look deeper. I mount this filesystem on a client system, then try to create a 16 GiB file on it using dd. While creating the file I watch the server with top, and see that both the virtual memory use and resident set size of the cosd instance grow to ~4 GiB, and a short time later cosd dies by oom-killer: May 26 16:12:28 sasa008 kernel: [ 902.544418] Killed process 6621 (cosd) vsz:4319672kB, anon-rss:3832152kB, file-rss:208kB The osd has a 100 GiB partition for its data. Am I maybe doing something wrong? Is there anything else I can do to help debug this?
