1.2.6 is about three years old. I would recommend you upgrade to atleast 1.2.9. Looking at the release logs, I do see a similar issue fixed in 1.2.7. http://oss.oracle.com/projects/ocfs2/news/article_16.html But I doubt you are hitting that issue as a leak in the kernel can only be reclaimed by a reboot. _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com http://oss.oracle.com/mailman/listinfo/ocfs2-users
