I was not able to reproduce the problem in that setup. What's the workload you're running, precisely? I would not generally expect multiple accesses to a sqlite database to work *well*, but offhand I'm not entirely certain why it would work differently between the kernel and userspace clients. (Probably something to do with the timing of the shared requests and any writes happening.) -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
