Hi Daigo, In the Ceph project we use tcmalloc by default for its much-improved (over the standard) handling of memory fragmentation under our workload. Unfortunately, one of our users seems to have a discovered a memory leak when running the standard Debian squeeze packages: http://tracker.ceph.com/issues/5375#note-8 Note that while tcmalloc is reporting it has an 80MB heap from the OS (of which about half is in use), the OS believes the process has 1GB allocated. This mismatch is not behavior we've seen before, and when the user backported the wheezy version of libgoogle-perftools and rebuilt the problem did not resurface. Is this an issue you've encountered before? We'd like to identify the cause for future reference with our users, or in case the issue recurs in future versions of the library. -Greg -- To unsubscribe from this list: send the line "unsubscribe ceph-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
